HALL EFFECT LATCH
General Description
Features
AH1751 is a single-digital-output Hall-effect sensor for high
temperature operation. The device includes an on-chip Hall
voltage generator for magnetic sensing, an amplifier to amplify
Hall voltage, and a comparator to provide switching hysteresis for
noise rejection, and an open-collector output pre-driver.
An internal band-gap regulator is used to provide temperature
compensated supply voltage for internal circuits and allows
a wide operating supply range.

Bipolar Hall Effect Latch Sensor
3.5V to 20V DC Operation Voltage
Open Collector Pre-Driver
50mA Output Sink Current
Chip Power Reverse-Connection Protection
Operating Temperature: -40oC~125oC
SIP3, SC59 and SC59R (Commonly known as SOT23
in Asia): Available in “Green” Molding Compound
(No Br, Sb)
While the magnetic flux density (B) is larger than threshold Bop,
the OUT pin turns on (low). If B removed toward Brp, the OUT pin
is latched “on” state prior to B < Brp. When B < Brp, the OUT pin
go into “off ” state.
