DRV110 - 6- to 48-V DC Current Controller

General Description

The DRV110 device is a PWM current controller for solenoids.

The device is designed to regulate the current with a well-controlled waveform to reduce power dissipation.

The solenoid current is ramped up fast to ensure opening of the valve or relay.

Key Features

  • 1 Internal Zener Diode on Supply Pin for HighVoltage Operation.
  • 120- and 230-V AC Supply Through Rectifier and RS Resistor.
  • 24-V, 48-V, and Higher DC Supply Through RS Resistor.
  • Drives an External MOSFET With PWM to Control Solenoid Current.
  • External Sense Resistor for Regulating Solenoid Current.
  • Fast Ramp-Up of Solenoid Current to Ensure Activation.
  • Solenoid Current is Reduced in Hold Mode for Lower Power and Thermal Dissipation.
