GENERAL DESCRIPTION

MA7026 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).
