AH41
AH41 is BIPOLAR HALL-EFFECT POSITION SENSORS manufactured by BCD.
Description
The AH41 is an integrated Hall-effect latched sensor designed for electronic mutation of brushless DC motor applications. The device includes an on-chip Hall voltage generator for magnetic sensing, a parator that amplifiers the Hall voltage, and a Schmitt to provide switching hysteresis for noise rejection and open-collector output. An internal bandgap regulator is used to provide temperature pensated supply voltage for internal circuits and allows a wide operating supply range.
A north pole of sufficient strength will turn the output ON. In the absence of a magnetic field, the output is OFF.
This IC is available in TO-92S-3 package.
