AH3965/AH3966/AH3967/AH3968

DUAL HALL-EFFECT LATCH

WITH SPEED & DIRECTION OUTPUT

Description

Pin Assignments

The AH3965/AH3966/AH3967/AH3968 is a high voltage dual Hall-

effect sensor designed for the applications that require accurate speed

and direction sensing. To support the wide range of the 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 AH3965/AH3966/AH3967 provides speed and

direction outputs, while the AH3968 provides two independent outputs

at Q1 and Q2.

DIR/Q1

SP/Q2

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

with a Zener clamp on the supply.

TSOT25 (Type A1)

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.
