Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community Reference Design DRV120 SLVSBG3C – JUNE 2012 – REVISED JUNE 2016 DRV120 Single-Channel Relay, Solenoid, Valve Low-Side Driver With.

General 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.

Key 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.
