AH180N-WSG-7

NOT RECOMMENDED FOR NEW DESIGN USE AH1806 AH180N MICROPOWER OMNIPOLAR HALL-EFFECT SWITCH Description Pin Assignments ( Top View ) The AH180N is a high sensitivity, micro power Omnipolar Hall Effect switch IC designed for portable and battery powered equipment such 3. OUTPUT as cellular phones, PDA’ s and portable PC’ s. Based on two sensitive Hall Effect plates and a chopper stabilized architecture the AH180N GND 2. provides a reliable solution over the whole operating range. To 1. VDD support portable and battery powered equipment the design has been optimized to operate over the supply range of 2.5V to 5.5V and SC59 and TSOT23 consumes only 24µA with a supply of 3V. ( Top View ) The single open drain output can switched on with either a North or NC 1 is larger than operate point (Bop) the output is switched on (pulled GND 2 low). The output is turned off when B becomes lower than the release NC 3 5 OUTPUT 4 VDD South pole of sufficient strength. When the magnetic flux density (B) point (Brp). The output will remain off when there is no magnetic field.
