Datasheet - production data
Description
The device 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® M0-7 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 lead-frames.
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. A SEL0 pin is
available to address the information available on
the CS to the microcontroller. The CS pin allows
to monitor the motor current by delivering a
current proportional to the motor current value.
The PWM, up to 20 kHz, allows 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.

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 4 V.
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
Ron 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.
