High Sensitivity Micropower Omnipolar Hall-effect Switch
General Description
High sensitive omnipolar operation.
Micropower operation.
AW86502STR is a high-sensitivity micropower
Omnipolar Hall effect switch IC. It has open-drain
outputs that can become high impedance or drive
ground, and an external pullup resistor must be
used. AW86502STR uses a hibernating clocking
system to reduce power consumption, which the
total power consumption in normal operation is
typically 0.8A with a 1.8V power source. Mainly
designed for portable devices such as laptop
computer, smartphone and bluetooth headset etc.
The supply range of AW86502STR is 1.6V to 5.5V
to support portable equipment. To minimize PCB
space, the AW86502STR has ultra small package:
SOT23-3L .
Ultra small package: SOT23-3L.
On board voltage regulator for 1.6V to 5.5V
range.
Wide operating temperature range: -40 ℃ to
85℃.
ESD (HBM) > 6KV.

position switches in consumer products.
When the magnetic field strength is greater than
Bop, then the device output is pulled low; When the
magnetic field strength is less than Brp, then the
device output is pulled high; When the magnetic
field strength is between Bop and Brp, then the
device output remains in the previous state.

Note: Maximum and minimum parameters values over operating temperature range are not tested
in production. They are guaranteed by design, characterization and process control. The magnetic
field strength (Gauss) required to cause the switch to change state (operate and release) will be
as specified in the magnetic characteristics. To test the switch against the specified magnetic
characteristics, the switch must be placed in a uniform magnetic field.
