AH8115
HALL SWITCH
LOW CURRENT CONSUMPTION, HIGH SENSITIVITY CMOS HALL IC
REV1.0 - JUN 2013 RELEASED - - 1 -
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 Q 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 behaviour 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.
