DRV120 - Valve Low-Side Driver

Description

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.

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.
  • Peak Current, Keep Time at Peak Current, Hold Current, and PWM Clock Frequency Can Be Set Externally. They Can Also Be Operated at Nominal Values Without External Components.
  • Internal Supp.
