FS72X/FS72XY is a Hall sensor with latched digital output. It’s suitable for electronic commutation of brushless DC motor applications. The FS72X/FS72XY uses a chopper amplifier for magnetic signal amplification, which can achieve a low offset and thus precise magnetic switching thresholds.
If a magnetic flux density larger than threshold Bop,NO is turned on(low). The output state is held until a magnetic flux density reversal falls below Brp causing NO to be turned off (high)
