DIODES AH180-WG-7

The 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 24μW 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-3 (Ammo Pack), SIP-3 (Bulk Pack) and SC59 packages.
