PROGRAMMABLE MICROPOWER OMNIPOLAR

HALL-EFFECT SENSOR SWITCH

Description

Pin Assignments

The AH1892 is a micropower magnetic range selectable (Bop/Brp)

Omnipolar Hall effect switch IC with internal pull up and pull down

capability, designed for consumer equipment ranging from portable

and battery powered cellular phones and portable PCs to home

appliances and industrial applications. To support battery powered

equipment and low voltage microcontrollers, the AH1892 can operate

over the supply range of 1.6V to 3.6V and uses a hibernating clocking

system to minimize the power consumption. The average supply

current is only 4.3µA typical at 1.80V. Due to the application diversity,

the AH1892 has an 8kV ESD rating on the supply and output pins. To

minimize PCB space the AH1892 is packaged in the small CSP

package (0.71mm x 0.71mm) or SOT553 leaded package

U-WLB0707-4

The output is activated with either a north or south pole of sufficient

magnetic field strength. The user can select one of two magnetic

sensitivity bands via the BSEL pin without the addition of any external

components allowing a flexible but small solution. The band select

can be hardwired or be changed on the fly via a logic source such as

a micro-controller. When the magnetic flux density (B) is larger than

operate point (Bop), the output will be turned on (pulled low) and held

until B is lower than release point (Brp).
