AH1389

ULTRA SENSITIVE DUAL OUTPUT

UNIPOLAR HALL EFFECT SWITCH

Description

Pin Assignments

The AH1389 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 AH1389 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 4μA at 1.85V. The AH1389 has an 8kV ESD rating on the supply

and output pins. To minimize PCB space the AH1389 is packaged in

small low profile X2-DFN1410-4.

Output1(N-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(-25G

typical). The Output1 is held low until B rises above the North field

release point B_RPN(-20G typical).Similarly, the Output2 will operate

(pulled low) when B to the part marking surface rises above South field

operate point B_OPS(25G typical) and is held low until B falls below the

South field release point B_RPS(20G typical).
