AH8115

HALL SWITCH

LOW POWER, HIGH SENSITIVITY, CMOS HALL SWITCH

DESCRIPTION

FEATURES

The AH8115 is an integrated hall-effect sensor

designed specifically to meet the requirements of

low-power devices. e.g. as an On/Off switch in

cellular flip-phones, with battery operating voltages

of 2.0V-5.5V.

Precise magnetic switching points and high

temperature stability are achieved through the unique

design of the internal circuit. An onboard clock

scheme is used to reduce the average operating

current of the IC. During the operate phase the IC

compares the actual magnetic field detected with the

internally compensated switching points. The output

Voltage is switched at the end of each operating

phase. During the Stand-by phase the output stage

is latched and the current consumption of the device

reduced to some μA.

The IC switching behavior is omnipolar, it can be

switched on with either the north or south pole of a

magnet.

AH8115 is higher sensitivity of magnetic induction

than AH8113, it can be used in security systems、

sensing magnet smaller occasions.

The AH8115 is available in TSOT-23 package.
