AH1822 Datasheet Micropower Omnipolar Hall-effect Sensor Switch

Manufacturer: Diodes Incorporated

Overview: AH1822 MICROPOWER OMNIPOLAR HALL-EFFECT SENSOR SWITCH.

General Description

AH1822 is prised of two Hall effect plates and an open-drain output driver, mainly designed for battery-operation, hand-held equipment (such as Cellular and Cordless Phone, PDA).

The total power consumption in normal operation is typically 24µW with a 3V power source.

Either north or south pole of sufficient strength will turn the output on.

Key Features
