5140 General Description

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.

Each sensor/driver includes a magnetic sensing Hall voltage generator, operational amplifier, Schmitt trigger, voltage regulator, and an open-collector, high-gain Darlington power output stage. The regulator allows use of the device with supply voltages of 4.5 V to 28 V. On-chip compensation circuitry stabilizes switch-point performance over temperature. The magnetic operation of this device is similar to that of the A3141E- Hall-effect switch.

The sensitive magnetic switch point coupled with the power output,current limiting, and thermal limiting circuitry allow the UGQ5140K to magnetically actuate various loads without requiring any external components.

The UGQ5140K is rated for operation over an extended temperature range of -40°C to +85°C. It is supplied in a four-pin mini-SIP plastic package, 0.200" (5.08 mm) wide, 0.130" (3.30 mm) high, and 0.060" (1.54 mm) thick.
