DRV120 Overview
The DRV120 device is a PWM current driver for solenoids. The device is designed to regulate the current with a well-controlled waveform to guarantee activation and to reduce power dissipation at the same time. The solenoid current is ramped up fast to ensure opening of the valve or relay.
