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.

Name
Description
Logic control
Allows the turn-on and the turn-off of the high-side and the
low-side switches according to the truth table.
Undervoltage
Shuts down the device for battery voltage lower than 5V.
High-side and low-side clamp voltage
Protect the high-side and the low-side switches from the
high voltage on the battery line.
High-side and low-side driver
Current limitation
Drive the gate of the concerned switch to allow a proper
RDS(on) for the leg of the bridge.
Limits the motor current in case of short circuit.
High-side and low-side overtemperature
protection
In case of short-circuit with the increase of the junction
temperature, it shuts down the concerned driver to prevent
degradation and to protect the die.
Low-side overload detector
Detects when low side current exceeds shutdown current
and latches off the concerned Low side.
