AH3761高灵敏度霍尔效应锁存器
分享资料个
The AH3761 is an integrated Hall effect latched 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 drain 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 is held until a magnetic flux density reversal falls below Brp causing DO to be turned off （high）。
