AH175 HALL EFFECT LATCH FOR HIGH TEMPERATURE Features • • • • • • • • • Bipolar Hall Effect Latch Sensor 3.5V to 20V DC Operation Voltage Open Collector Pre-Driver 25mA Output Sink Current Chip Power Reverse-Connection Protection o o Operating Temperature: -40 C~150 C Lead Free Finish/RoHS Compliant for Lead Free products (Note 1) Lead Free Packages: SIP-3L, SC59-3L Green Package: SC59-3L 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 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 is latched “on” state prior to B < Brp. When B < Brp, the OUT pin goes into “off ” state.
