DRV110APWR Description

The DRV110APWR is a PWM current controller for solenoids. The DRV110APWR controller is designed to regulate the current with a well-controlled waveform to reduce power dissipation. The solenoid current is rapidly increased to guarantee that the valve or relay opens. Following initial ramping, the solenoid current is held at a peak value to ensure proper operation, before being decreased to a lower hold level to minimize thermal problems and reduce power dissipation.
