AH1388

ULTRA SENSITIVE DUAL OUTPUT

UNIPOLAR HALL EFFECT SWITCH

Description

Pin Assignments

The AH1388 is a miniature micropower magnetic Unipolar Hall effect

switch IC with dual outputs specifically designed for portable and battery

powered consumer equipment to home appliances and industrial

applications. To support battery powered equipment and low voltage

microcontrollers, the AH1388 can operate over the supply range of 1.6V

to 3.6V and uses a sleep function to give an average supply current of

only 12μA at 1.85V. To minimize PCB space, the AH1388 is packaged in

small low profile X2-DFN1410-4.

Output1 (North-Pole)

A North pole of sufficient strength will turn Output1 on and a South pole

of sufficient strength will turn on Output2. The Output1 is turned on (pulled

low) when the magnetic flux density (B), perpendicular to the part

marking surface, falls below North field operate point B_OPN(-17G typical).

The Output1 is held low until B rises above the North field release point

B_RPN(-11G typical). Similarly, the Output2 will operate (pulled low) when

B to the part marking surface rises above South field operate point B_OPS

(17G typical) and is held low until B falls below the South field release

point B_RPS(11G typical).
