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).
