Description
The VNH5200AS-E is a full bridge motor driver
intended for a wide range of automotive
applications. The device incorporates a dual
monolithic high-side driver and two low-side
switches.
Both switches are designed using
STMicroelectronics’ well known and proven
proprietary VIPower® M0 technology that allows
to efficiently integrate on the same die a true
Power MOSFET with an intelligent
signal/protection circuitry. The three dies are
assembled in SO-16N package on electrically
isolated leadframes.
Moreover, its fully symmetrical mechanical design
allows superior manufacturability at board level.
The input signals INA and INB can directly
interface 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, enables one leg of the
bridge. Each DIAGA/ENA provides a feedback
digital diagnostic signal as well. The normal
operating condition is explained in the truth table.
The CS pin allows to monitor the motor current by
delivering a current proportional to its value.

Description
Signalizes the abnormal behaviour of the switch (output
shorted to ground or output shorted to battery) by pulling
down the concerned ENx/DIAGx pin.
Limits the power dissipation of the high-side driver inside
safe range in case of short to ground condition.
