STMicroelectronics L9960 Automotive ETC H-Bridges
STMicroelectronics L9960 Automotive ETC H-Bridges are AEC-Q100 qualified and can be used in resistive and inductive loads for automotive applications. These applications include 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 the 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.
