MA177

Single Output Hall Effect Latch



GENERAL DESCRIPTION

MA177 is an integrated Hall effect latched sensor designed for electronic commutation of

brush-less DC motor applications. The device is using HV BCD process includes an on-chip

Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a

Schmitt trigger to provide switching hysteresis for noise rejection, and open-collector output. An

internal band-gap regulator is used to provide temperature compensated supply voltage for

internal circuits and allows a wide operating supply range.

If a magnetic flux density larger than threshold Bop, OUT is turned on(low). The output state is

held until a magnetic flux density reversal falls below Brp causing OUT to be turned off (high).


