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 approximately 900 mA.
A sensitive magnetic threshold allows the device to be used in conjunction with inexpensive magnets or in applications that require relatively large operating distances.
