STMicroelectronics L9374 Four Channel Valve Driver Datasheet
The L9374 is a four-channel low-side driver with integrated recirculation diodes designed for valve control applications. The device features two PWM-controlled channels and two current-controlled channels, all equipped with protection and diagnostic capabilities. Switching is programmable via a Serial Peripheral Interface (SPI), and the main time base is provided by an external clock.
