UH378 - COMPLEMENTARY OUTPUTS HALL EFFECT LATCH IC

General 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.

Key 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.

UNISONIC TECHNOLOGIES CO., LTD UH378 LINEAR INTEGRATED CIRCUIT COMPLEMENTARY OUTPUTS HALL EFFECT LATCH IC  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 BOP or the magnetic flux density is lower than BRP.  FEATURES * Widen Power Supply range from 3V ~ 20V. * On-chip Hall sensor with excellent hysteresis. * Build-in reverse protection diode.
