Description
The VHN5019A-E is a full bridge motor driver
intended for a wide range of automotive
applications. The device incorporates a dual
monolithic high-side drivers and two low-side
switches. The high-side driver switch is designed
using STMicroelectronics’ well known and proven
proprietary VIPower® M0 technology that allows
to efficiently integrate on the same die a true
MultiPowerSO-30™
Power MOSFET with an intelligent
signal/protection circuit.
The three dice are assembled in
MultiPowerSO-30 package on electrically isolated
lead-frames. This package, specifically designed
for the harsh automotive environment offers
improved thermal performance thanks to exposed
die pads. The input signals INA and INB can
directly interface to the microcontroller to select
the motor direction and the brake condition.
The DIAGA/ENA or DIAGB/ENB, when connected
to an external pull-up resistor, enable one leg of
the bridge. They also provide a feedback digital
diagnostic signal. The CS pin allows to monitor
the motor current by delivering a current
proportional to its value when CS_DIS pin is
driven low or left open. The PWM, up to 20 KHz,
lets us to control the speed of the motor in all
possible conditions. In all cases, a low-level state
on the PWM pin turns-off both the LSA and LSB
switches. When PWM rises to a high-level, LSA or
LSB turn-on again depending on the input pin
state.
Output current limitation and thermal shutdown
protects the concerned high-side in short to
ground condition.
The short to battery condition is revealed by the
overload detector or by thermal shutdown that
latches off the relevant low-side.
Active VCC pin voltage clamp protects the device
against low energy spikes in all configurations for
the motor.
CP pin provides the necessary gate drive for an
external n-channel PowerMOS used for reverse
polarity protection.
