APX9131
Application Information
It is strongly recommended that an external bypass ca-
pacitor be connected (in close to the Hall sensor) be-
tween the supply and the ground of the device to reduce
both external noise and noise generated by the chop-
per-stabilization technique. This is especially true due
to the relatively high impedance of battery supplies.The
output is an open drain output, it must be connected a pull-
up resistor to a supply voltage which is lower than 5V,
connect a 50kΩ resistor to VDD in common use.
