Description

AH1751 is a single-digital-output Hall-effect sensor for high temperature operation. The AH1751 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.

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 of AH1751 is latched "on" state prior to B < Brp. When B < Brp, the OUT pin go into " off " state.
