DRV120 Datasheet (Texas Instruments)

DRV120, Valve Low-Side Driver

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.

DRV120 Features

* 1 Integrated MOSFET With PWM to Control Solenoid Current

* Integrated Sense Resistor for Regulating Solenoid Current

* Fast Ramp-Up of Solenoid Current to Guarantee Activation

* Solenoid Current is Reduced in Hold Mode for Lower Power and Thermal Dissipation
