AUTOMOTIVE DUAL HALL EFFECT LATCH

WITH SPEED & DIRECTION OUTPUT

Description

Pin Assignments

The AH3965Q/AH3966Q/AH3967Q/AH3968Q is an AEC-Q100

qualified high voltage dual Hall-effect sensor designed for the

applications that require accurate speed and direction sensing. To

support wide range of demanding applications, the design has been

optimized to operate over the supply range of 2.7V to 27V. With

chopper stabilized architecture and an internal bandgap regulator to

provide temperature compensated supply for internal circuits, the

AH3965Q/AH3966Q/AH3967Q provides speed and direction outputs,

while AH3968Q provides two independent outputs at Q1 and Q2.

SP/Q2

For robustness and protection, the device has a reverse blocking diode

with a Zener clamp on the supply.

In the occasion of a supply voltage drop to minimum threshold point,

undervoltage lockout protection would be triggered to freeze the

device, which prevents the electrical malfunction from affecting the next

magnetic measurement circuits, and the output current state updated

is always based on the proper accurate measurement result.
