Version 1.1, Nov 2023

Automotive Fully Integrated H-bridge Motor Driver

 Features

 Applications



AEC-Q100 qualified

Automotive brushed DC motors and solenoids



−

Device ambient temperature: -40°C ≤ T_A

Zone control unit (ZCU)



≤ 125°C

Hidden door handles



Device junction temperature: -40°C ≤ T_J

≤ 150°C

Side mirror modules



Electric spoiler adjustment



Operating voltage: 4 to 28 V, 40 V abs. max

Output current: 12 A

Door lock, child lock, tail gate lock



On board charger

R_DS(on): 85 mΩ typ per half bridge

3 V CMOS-compatible inputs

PWM operation up to 20 kHz

Very low standby current, 1.5 μA max at 25°C

Protections:

 Description

The device is a fully integrated H-bridge motor driver

intended for a wide range of automotive applications.

The design of monolithic die in a power package

offers better robustness and higher reliability.

−

Cross-conduction protection

Overvoltage clamp

Undervoltage shutdown

Current limitation

The direction and brake operation of the motor are

simply controlled by applying digital signals to the IN_A

and IN_B.

Power limitation

Thermal shutdown

Output short to ground and short to V_CC

Loss of ground and loss of V_CC

The CS pin allows to monitor the motor current by

delivering a current proportional to the motor current

value, and it also develops a voltage flag for a failure

on the relevant output in the ON state as well as the

OFF state. The independent PWM pin, up to 20 kHz,

allows to control the speed of the motor easily in all

possible conditions. In all cases, a low level state on

the PWM pin turns off both the LSA and LSB

switches.



CS diagnostic functions:

−

Analog motor current feedback

OFF-state open load detection

Output short to ground detection

Output short to VCC detection

Thermal shutdown indication



Flexibility of use as full bridge, dual half bridge

and multi-motor driving configuration

 Simplified Schematic

 Package Information
