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.
