Overview
OBSOLETE – PART DISCONTINUED PART OBSOLETE USE AH3774 AH3761 HIGH SENSITIVITY HALL EFFECT LATCH Description 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).
