5 Description and Electrical Characteristics
5.1 MOSFET Driver
5.1.1
Output Stages
The 3 low side and 3 high side powerful push-pull output stages of the TLE7185E are all floating blocks, each with
its own source pin. This allows the direct connection of the output stage to the source of each single MOSFET,
allowing a perfect control of each gate-source voltage even when 200A are driven in the bridge with rise and fall
times below 1µs.
All 6 output stages have the same output power and thanks to the used bootstrap principle they can be switched
all up to 30kHz.
To ensure high gate voltages even at low battery voltages, the driver IC has an integrated charge pump. It allows
operation of normal level MOSFETs down to 5.5V supply.
Each output stage has its own short circuit detection block. For more details about short circuit detection see

TLE7185E
Description and Electrical Characteristics
conditions clearly less than 9V to the gate of the external MOSFETs, increasing their RDSon and the associated
power dissipation.
The TLE7185E has a charge pump circuitry for external capacitors.
The operation of the charge pump is independent upon the pulse pattern of the MOSFETs.
The output of the charge pump is regulated to about 12V.
The output of the charge pump supplies the output stages for the low side MOSFETs with sufficient voltage to
assure 10V at the MOSFETs´ gate even if the supply voltage is below 10V.
It supplies as well the bootstrap circuitry for the high side output stages. Off course the bootstrap principle leads
to the fact that the bootstrap capacitors needs to be charged regularly. The charging time for the bootstrap
capacitor is specified (duty cycle HS) as well as the current consumption from the bootstrap capacitor in
permanent “on” condition.
The charge pump is only deactivated when the device is put into sleep mode via INH.
During Start Up of the device it is not allowed to have any PWM patterns at the ILx and IHx pins until the charge
pumps have ramped up to their final values or it is recommended to keep the ENA pin low.
The size of the charge pump capacitor (pump capacitors CCP as well as buffer capacitor CCB) can be varied
between 1 µF and 4.7 µF. Yet, larger capacitor values result in higher charge pump voltages and less voltage
ripple on the charge pump buffer capacitor CB. Besides the capacitance values the ESR of the buffer capacitor
CB determines the voltage ripple as well. It is recommended to use buffer capacitor CB that has small ESR.
Please. see also Chapter 5.1.3 for capacitor selection.
5.1.3
Sleep Mode
When the INH pin is set to low, the driver will be set to sleep mode. The INH pin switches off the complete supply
structure of the device and leads finally to an under voltage shut down of the complete driver. Enabling the device
with the INH pin means to switch on the supply structure. The device will run through power on reset during wake
up. It is recommended to perform a Reset by ENA after Wake up to remove possible ERR signals; Reset is
performed by keeping one or more ENA pins low until the charge pump voltages have ramped up.
Enabling and disabling with the INH pin is not very fast. For fast enable / disable the ENA pin is recommended.
When the TLE7185E is in INH mode (INH is low) or when the supply voltage is not available on the Vs pin, then
the driver IC is not supplied, the charge pump is inactive and the charge pump buffer capacitor as well as the
bootstrap capacitors are discharged.

TLE7185E
5.2 Protection and Diagnostic Functions
5.2.1
Short Circuit Protection
The TLE7185E provides a short circuit protection for the external MOSFETs. It is a monitoring of the drain-source
voltage of the external MOSFETs. As soon as this voltage is higher than the short circuit detection level, a timer
will start to run.
The short circuit detection level is programmable from outside by applying a voltage divider at the SCDL pin. The
applied voltage at this pin will be used as short circuit detection level up to the specified maximum level. Above
this level the short circuit detection is deactivated.
After a delay tSCP all external MOSFETs will be switched off until the driver is reset by the ENA pin. The error flag
is set.
The drain-source voltage monitoring of the short circuit detection for a certain external MOSFET is active as soon
as the corresponding input is set to "on" and the dead time is expired.
For safety reasons a pull up resistor at the SCDL pin assures that in case of an open pin the SCDL voltage is pulled
to high levels. In this case, the SCD is deactivated an error signal is set. This function is self clearing when the
voltage at SCDL returns to the specified level.
The short circuit detection filter is realized with a capacitor, which is discharged with a current source with X µA.
In case the output stage is switched on and the VDS of the MOSFET is still above SCDL, the capacitor is charged
with a current source with Y µA. If this capacitor is charged to a specific voltage level, the short circuit is detected,
the ERR signals are set and the MOSFETs switched off. The SCD charge and discharge ratio is defined as
(Y-X)/X.
This ratio defines down to which duty cycle the short circuit can be detected.
It has to be considered that the high side and the low side output of one phase are working with the same capacitor,
defining the maximum switching time, which is allowed without short circuit detection. This maximum allowed
switching time in normal operation is defined by dnoSCD/2*fPWM.
This behavior is specified as “maximum duty cycle for no short circuit detection” and “minimum duty cycle for
periodic short circuit detection”
5.2.2
Dead Time and Shoot Through Protection
In bridge applications it has to be assured that the external high side and low side MOSFETs are not "on" at the
same time, connecting directly the battery voltage to GND. The dead time generated in the TLE7185E is fixed to
a minimum value if the DT pin is connected to GND. This function assures a minimum dead time if the input signals
coming from the µC are faulty.
The dead time can be increased beyond the internal fixed dead time by connecting the DT pin via a dead time
resistor RDT to GND - the larger the dead time resistor the larger the dead time (for details pls. see the “Dynamic
Characteristic” table in the MOSFET driver section).
The exact dead time of the bridge is usually controlled by the PWM generation unit of the µC.
In addition to this dead time, the TLE7185E provides a locking mechanism, avoiding that both external MOSFETs
of one half bridge can be switched on at the same time. This functionality is called shoot through protection.
If the command to switch on both high and low side switches in the same half bridge is given at the input pins, the
command will be ignored.

TLE7185E
5.2.3
Shoot Through Option
The TLE7185E offers the possibility to switch off the Shoot Through Protection by setting the STOE pin to high
and in the same time all IHX to low and all ILX to high. Only if all 7 conditions are fulfilled in the same time, the
Shoot Through Protection and the Short Circuit Detection is deactivated and allows to switch on all 6 external
MOSFETs.
If STOE is set to high, an error signal is set.
5.2.4
Under Voltage Lock Out on Vs
The TLE7185E has an integrated under voltage lock out, to assure that the behavior of the device is predictable
in all supply voltage ranges.
If the supply voltage at VS reaches the under voltage lock out level for a minimum specified filter time, the gate-
source voltage of all external MOSFETs will be actively pulled to low. In this situation the short circuit detection of
this output stage is deactivated to avoid a latching shut down of the driver. Furthermore, the charge pump will be
deactivated.
As soon as the supply voltage recovers, the output stage condition will be aligned to the input patterns
automatically. This allows to continue operation of the motor in case of under voltage shut down without a reset
by the µC.
5.2.5
Under Voltage warning on CB
In addition to the under voltage lockout, the TLE7185E provides an integrated under voltage warning.
The purpose of this warning is to inform the user about possible low gate voltages.
If the voltage of a charge pump buffer capacitor CB reaches the under voltage warning level for a minimum
specified filter time, an Errors signal is set.
As soon as the charge pump buffer voltage recovers, the Error signal will be removed automatically.
5.2.6
Over Voltage Warning on Vs and / or VDH
The TLE7185E has an integrated over voltage warning to avoid destruction of the IC at high supply voltages. The
voltage is observed at the VS and the VDH pin. When one of them or all of them exceed the over voltage warning
level for more than the specified filter time an Error signal is set. It is in the responsibility of the user to react to this
signal to avoid damage of the driver by exceeding the max ratings. The Errors signal is self clearing.
The basic driver functions will work even above this over voltage warning level as long as no maximum rating is
violated. At such high voltages, the specified values will not be guaranteed.
5.2.7
Over Temperature Warning
If the junction temperature is exceeding the over temperature level an error signal is given as warning. The driver
IC will continue to operate in order not to disturb the application.
The warning is removed automatically when the junction temperature is cooling down.
It is in the responsibility of the user to protect the device against over temperature destruction.
5.2.8
ERR Pins
The TLE7185E has two status pins to provide diagnostic feedback to the µC. The outputs of these pins are open
drain outputs with integrated pull up resistors to the internal 5V supply (see Figure 4 ). The outputs are either high
or low.

Reset of ERROR Registers and Disable
The TLE7185E can be reseted by the enable pin ENA. If the ENA pin is pulled to low for a specified minimum time,
the error registers are cleared. During reset (ENA = low) the driver outputs are disabled and the external
MOSFETs are switched off actively. Furthermore, the Short Circuit Detection SCD is deactivated as long as ENA
= low.
During disable (ENA = low) any error is shown. However, the Short circuit detection error is reset (error is cleared)
and can not reoccur as the output stages which drive the external MOSFETs are disabled.
In case of under voltage lockout, the ERR pins deviate from the table above as the charge pump is not active and
the TLE7185E is not biased properly.
