Overview

The DRV110 device provides a PWM current controller for use with solenoids. The device provides a quick ramp to a high peak current value in order to ensure opening of the valve or relay. The current is held for a programmable time and then lowered to the hold current value to maintain the open state of the valve or relay while reducing the total current consumption. Peak current duration, peak current amount, hold current amount (in the 14-pin package), and PWM frequency can all be controlled by external components or used at default levels by omitting these components (except peak current duration).

Enable and disable of the switch is controlled by the EN pin. The EN pin contains an internal resistor network to set the pin to logic HIGH when the EN pin is floating. This feature can be used for situations where a control signal is not required and the solenoid is only energized when a supply voltage is present. Such applications could be valves or contactors.

The DRV110 also features a wide VIN range with an internal bypass regulator to maintain VIN at an acceptable level. Finally, the 14-pin package features an open-drain pull-down path on the STATUS pin which is enabled as long as undervoltage lockout or thermal shutdown has not triggered.
