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).
