MICROPOWER OMNIPOLOAR HALL-EFFECT SENSOR SWITCH
Description
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 Hall-Effect 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.
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.
The AH180 is available in SIP-3L, SC59, DFN2020-3, and DFN2020-
6 packages.
