Description
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
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).
