AH276Q - COMPLEMENTARY OUTPUT HALL EFFECT LATCH

General Description

AH276 are integrated Hall sensors with output drivers, mainly designed for electronic commutation of brush-less DC Fan.

This IC internally includes the regulator, protecting diode, Hall plate, amplifier, comparator, and a pair of complementary open-collector outputs (DO, DOB).

Key Features

  • On-chip Hall sensor with two different sensitivity and hysteresis settings for AH276 Built-in protecting diode only for chip reverse power connecting -20°C to 85°C operating temperature Lead Free Finish/RoHS Compliant for Lead Free products (Note 1) Lead Free Package: SIP-4L General.

This IC internally includes the regulator, protecting diode, Hall plate, amplifier, comparator, and a pair of complementary open-collector outputs (DO, DOB). While the magnetic flux density (B) is larger than operate point (Bop), DO will turn on (low), and meanwhile DOB will turn off (high).
