GENERAL DESCRIPTION
MA7080 is a dual-channel, bipolar switch with two Hall effect sensing elements, each
providing a separate digital output for speed and direction signal processing capability. 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).
