Product Summary
The ATS177-PL-B-B is an integrated Hall effect latched sensor designed for electronic commutation of brush-less DC motor applications. The ATS177-PL-B-B 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 bandgap 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, DO is turned on(low). The output state of the ATS177-PL-B-B is held until a magnetic flux density reversal falls below Brp causing DO to be turned off (high).
