描述 Description

The device is an integrated H-Bridge for resistive

and inductive loads for automotive applications.

Target application includes throttle control

actuators, exhaust gas recirculation control

valves and general purpose DC motors such as

turbo, flap control and electric pumps.

The driving strategy is enhanced by configurable

PWM / DIR pins and IN1/IN2.

The H-Bridge contains integrated free-wheel

diodes. In case of freewheeling condition, the

low-side only is switched on in parallel of its diode

to reduce power dissipation.

The integrated Serial Peripheral Interface (SPI)

makes it possible to adjust device parameters, to

control all operating modes and read out

diagnostic information.
