GENERAL DESCRIPTION

MA41F is an integrated Hall effect latched sensor designed for electronic commutation of

brush-less DC motor applications. The device 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).
