H654 Datasheet (Unisonic Technologies) - COMPLEMENTARY OUTPUT HALL EFFECT LATCH

H654, COMPLEMENTARY OUTPUT HALL EFFECT LATCH

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

H654 Features

* Operate from 3.5V ~ 20V supply voltage.

* On-chip Hall sensor with two different sensitivity and hysteresis settings.

* High output sinking capability up to 300mA for driving large load.

* Lower current change rate reduces the peak output voltages during switching.

* Build-in p
