Dual High Side Switch
(7.0 mOhm)
07XSC200
The 07XSC200 is one in a family of devices designed for low-voltage
lighting or factory automation applications. Its two low RDS(ON)
MOSFETs (dual 7.0 m) can control two separate 55 W / 28 W bulbs,
and/or Xenon modules, and/or LEDs, and/or DC low voltage motors.
Programming, control and diagnostics are accomplished using a 16-bit
SPI interface. Its output with selectable slew rate improves
electromagnetic compatibility (EMC) behavior. Additionally, each
output has its own parallel input or SPI control for pulse-width
modulation (PWM) control if desired. The 07XSC200 allows the user to
program via the SPI, the fault current trip levels and duration of
acceptable inrush. The device has Fail-safe mode to provide fail-safe
functionality of the outputs in case of MCU damaged.
The 07XSC200 is packaged in a Pb-free power-enhanced 32 pins
SOIC package with exposed tab.
This device is powered by SMARTMOS technology.
Features
• Dual 7.0 mmax high side switch (at 25 °C)
• Operating voltage range of 6.0 to 20 V with sleep current < 5.0 µA,
extended mode from 4.0 to 28 V
• 8.0 MHz 16-bit 3.3 V and 5.0 V SPI control and status reporting with
daisy chain capability
• PWM module using external clock or calibratable internal oscillator
with programmable outputs delay management
• Smart overcurrent shutdown compliant to huge inrush current,
severe short-circuit, overtemperature protections with time limited
auto-retry, and Fail-safe mode, in case of MCU damage
• Output OFF or ON OpenLoad detection compliant to bulbs or LEDs
and short to battery detection. Analog current feedback with
selectable ratio and board temperature feedback.
