AH1751-WG-7-A

NOT RECOMMENDED FOR NEW DESIGN USE AH3774 AH1751 HALL EFFECT LATCH Description Pin Assignments 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 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. ( Top View ) 3. OUT 2. GND 1. VCC SIP3 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. ( Top View ) 3. Output GND 2. 1 .
