DESCRIPTION

The UTC UH378 is a Latch-Type Hall Effect sensor with built-in

complementary

output

drivers.

It’s

composed

of

internal

temperature compensation circuit and built-in protection diode to

prevent reverse power fault. It is aimed for brush-less DC Fan.

The outputs of the UH378 operate as the Hysteresis

Characteristics. The Outputs alternately switch between ON and

OFF when either the magnetic flux density is larger than threshold



FEATURES

* Widen Power Supply range from 3V ~ 20V.

* On-chip Hall sensor with excellent hysteresis.

* Build-in reverse protection diode.

* TTL and MOS IC are directly drivable by the output

* The life is semi permanent because it employs contact-less parts
