AH477
AH477 is SINGLE PHASE HALL EFFECT LATCH manufactured by BCD.
Product Brief SINGLE PHASE HALL EFFECT LATCH Description
The AH477 is an integrated Hall sensor with output driver designed for electronic mutation of brushless DC motor applications. The device includes an on-chip Hall sensor for magnetic sensing, an amplifier that amplifies the Hall voltage, a parator to provide switching hysteresis for noise rejection, a bi-directional drivers for sinking and driving large current load. It also includes an .. internal bandgap regulator to provide temperature pensated bias for internal circuits and allows a wide operating supply voltage range. Placing the device in a variable magnetic field, if the magnetic flux density is...
