Hall Effect Micro Switch IC

Anpec Electronics 

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.
