H654 General Description
The UTC H654 is integrated Hall sensors with complementary output drivers designed for electronic commutation of brushless DC Fan. It composed of an on-chip Hall voltage generator, a differential amplifier, Schmitt trigger, an open-collector output on a single chip. Furthermore, an internal bandgap regulator allows temperature compensated operations and a wide operating supply range. An on-chip protection diode is implemented to prevent reverse power fault.
When the magnetic flux density larger than threshold BOP, DO will be turned on(low) and DOB be turned off(high). The output state is held until the magnetic flux density is lower than BRP, and then DO is reversal to turned off and DOB turned on.
