Manufacturer: Diodes Incorporated

Overview: PRELIMINARY - CONFIDENTIAL.

General Description

NOT RECOMMENDED FOR NEW DESIGN USE AH3724Q AH3764Q HIGH-VOLTAGE, HIGH-SENQSITIVITY AUTOMOTIVE HALL-EFFECT LATCH Pin Assignments The AH3764Q is an AEC-Q100 qualified high-voltage, high-sensitivity Hall-Effect latch IC designed for brushless DC-motor commutation, speed measurement, angular or linear encoders and position sensors in automotive applications.

To support a wide range of demanding applications, the design is optimized to operate over the supply range of 3.0V to 28V.

With chopper stabilized architecture and an internal bandgap regulator to provide temperature compensated supply for internal circuits, the AH3764Q provides a reliable solution over the whole operating range.

Key Features

  • Bipolar Latch Operation (South Pole: On, North Pole: off).
  • High Sensitivity: Bop and Brp of +40G and -40G Typical.
  • Single Open-Drain Output with Overcurrent Limit.
  • 3.0V to 28V Operating Voltage Range.
  • Chopper Stabilized Design Provides.
  • Superior Temperature Stability.
  • Minimal Switch Point Drift.
  • Enhanced Immunity to Stress.
  • Good RF Noise Immunity.
  • Reverse Blocking Diode.
  • Zener Clamp on Supply and Output Pins.
