AH1751 Datasheet | Diodes Incorporated

Description 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 parator to provide switching hysteresis for noise rejection, and an open-collector output pre-driver. An internal band-gap regulator is used to provide temperature pensated 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.
