NONOTT RE RECOCOMMMMEENDED FONDED FOR NER NEWW D DEESSIGIGNN AH1751 USUSEE AAH3H3774774 HALL EFFECT LATCH Description Pin Assignments AH1751 is a single-digital-output Hall-effect sensor for high ( Top View ) temperature operation. The device includes an on-chip Hall voltage 3. OUT generator for magnetic sensing, an amplifier to amplify Hall voltage, and a comparator to provide switching hysteresis for noise rejection, 2. GND and an open-collector output pre-driver. An internal band-gap 1. V CC regulator is used to provide temperature compensated supply voltage for internal circuits and allows a wide operating supply range. SIP3 While the magnetic flux density (B) is larger than threshold Bop, the ( Top View ) 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. 3. Output GND 2. 1 .
