5140, PROTECTED POWERHALL SENSOR LAMP/SOLENOID DRIVER

5140 PROTECTED POWERHALL® SENSOR: LAMP/SOLENOID DRIVER 5140 PROTECTED POWERHALL® SENSOR LAMP/SOLENOID DRIVER The UGQ5140K unipolar Hall effect switch is a monolithic integrated circuit designed for magnetic actuation of low-power incandescent lamps or inductive loads such as relays or solenoids.

Included on chip is a Darlington power output that is capable of continuously sinking in excess of 300 mA.

Internal protection circuitry limits surge (lamp turn-ON) or fault currents to approx
