MICROPOWER, ULTRA-SENSITIVE HALL EFFECT SWITCH

Description

Pin Assignments

(Top View)

The AH1883 micropower Omnipolar Hall Effect switch IC is

designed for portable and battery powered equipment such

as cellular phones, cordless phones, camcorders, PDA’s, and

portable PC’s. Based on two high sensitivity Hall Effect plates

and chopper stabilized architecture, the AH1883 provides

reliable solution over the whole operating range.

To support portable and battery powered equipment the

design has been optimized to operate from 1.65V to 3.3V and

consumes 13uW typical with a supply of 1.8V. To minimize

PCB space the AH1883 incudes a push-pull output structure,

therefore does not require an external pull up resistor, and is

packaged in small low profile SOT553 and U-DFN2020-3

packages.

Either North or South pole of sufficient strength will turn the

output on. When the magnetic flux density (B) is larger than

operate (Bop) the output is switched on. 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.
