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 con-
tinuously 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 con-
junction 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 perfor-
mance 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 tempera-
ture 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.
