●The device is an integrated H-Bridge for resistive and inductive loads for automotive applications, such as throttle control actuators or exhaust gas recirculation control valves.
●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.
