AH175
HALL EFFECT LATCH FOR HIGH TEMPERATURE
General Description
Features
AH175 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

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
goes into “off ” state.
