General Description
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 bandgap regulator is used to provide
temperature compensated supply voltage for
internal circuits and allows a wide operating supply
range.
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.
