Hall Effect Sensor (AH59) , Magnetic Sensor, Sensor, Complementary Output Sensor
These sensor are an integrated hall sensor with output driver designed for electronic commutation of brushlessdc motor applications. The device includes an on-chip hall voltage generator for magnetic sensing, an amplifierthat amplifies the hall voltage, and a schmitt trigger to provide switching hysteresis for noise rejection, andcomplementary open-collector drivers for sinking large current loads. An internal band-gap regulator is used toprovide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. Ifa magnetic flux density larger than threshold bop, do is turned on (low) and dob is turned off (high). The outputstate is held until a magnetic flux density reversal falls below brp causing do to be turned off (high) and dobturned on.
