Diodes Incorporated ATS177
ATS177 is an integrated Hall-Effect latch sensor designed for electronic commutation of brush-less DC motor applications. The device 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. When the magnetic flux density (B) is larger than operate point (Bop), output is switched on (DO pin is pulled low).| Part No. | ATS177 |

DESCRIPTION
An internal bandgap regulator provides a temperature compensated supply voltage for internal circuits and allows a wide operating supply range. The output state is held on until a magnetic flux density reversal falls below Brp. When B is less than Brp, the output is switched off. The ATS177 is available in SIP-3L package.FEATURES
