U651 Datasheet (Unisonic Technologies) - SINGLE OUTPUT HALL EFFECT LATCH

U651, SINGLE OUTPUT HALL EFFECT LATCH

The UTC U651 is a Integrated Hall sensor with latch designed for electronic commutation of brushless DC motor applications.

The device includes an on-chip Hall voltage generator for magnetic sensing, a comparator that amplifies the Hall voltage, and a Schmitt trigger to provide switching hysteresis

U651 Features

* 3.5V to 20V operation

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

* Internal bandgap regulator allows temperature compensated operations and a wide operating voltage range.

* Open-Collector 25mA Output.

* Reverse Polarity Protection. BLOCK DIAGRAM 1
