AH180 MICROPOWER OMNIPOLAR HALL-EFFECT SENSOR SWITCH Description Pin Assignments AH180 is a micro-power Omnipolar Hall-Effect switch designed for portable and battery powered equipment such cellular phones, PDAs and portable PCs. Based on two HallEffect plates and a chopper stabilized architecture the AH180 provides a reliable solution over the whole operating range. To support portable and battery powered equipment the design has been optimized to operate over the supply range of 2.5V to 5.5V and consumes only 24uW with a supply of 3V. (Top View) 3. Output 2. GND 1. Vdd (SIP-3L) (Top View) The single open-drain output switches on with either a north or south pole of sufficient strength. When the magnetic flux density (B) is larger than operate point (Bop), output is switched on (Output pin is pulled low). The output is turned off when B becomes lower than the release point (Brp). The output will remain off when there is no magnetic field. 3. Output GND 2. 1 . Vdd SC59 6. NC ( Top View ) 3. GND (Top View) 5. GND 4.
