UHC182 Datasheet

SINGLE OUTPUT HALL EFFECT LATCH



DESCRIPTION

 

UTC UHC182 is an integrated Hall effect latched sensor

designed for electronic commutation of brush-less DC motor

applications. The device using HVCMOS process 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 for noise rejection, and open-collector output.

An internal band-gap regulator is used to provide temperature

compensated supply voltage for internal circuits and allows a wide

operating supply range.

If a magnetic flux density larger than threshold Bop, OUT is

turned on (low). The output state is held until a magnetic flux

density reversal falls below Brp causing OUT to be turned off

(high).

 

FEATURES

 

* 2.8V~30V DC operation voltage

* Temperature compensation

* Wide operating voltage range

* Open-Drain pre-driver

* 25mA maximum sinking output current.
