GENERAL DESCRIPTION

MA7024 is an integrated Hall-Effect latch sensor with pull-up resistor 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).
