1 / 6 page AH1751 HALL EFFECT LATCH AH1751 Rev. 1 - 2 1 of 6 APRIL 2008 www.diodes.com © Diodes Incorporated Features General 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 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. • Bipolar Hall Effect Latch Sensor • 3.5V to 20V DC Operation Voltage • Open Collector Pre-Driver • 50mA Output Sink Current • Chip Power Reverse-Connection Protection • Operating Temperature: -40 oC~125oC • Package: SIP3 • SIP3: Available in “Green” Molding Compound (No Br, Sb) 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. • Lead Free Finish/ RoHS Compliant (Note 1) Applications • Rotor Position Sensing • Current Switch • Encoder • RPM Detection Ordering Information AH1751 - X X X - X Packing P : SIP3 Package Lead Free Magnetic Characteristics A -B : Bulk (Note 4) -A : Ammo (Note 3) G : Green Tube/Bulk Ammo Box Device Package Code Packaging (Note 2) Quantity Part Number Suffix Quantity Part Number Suffix AH1751-P P SIP3 1000 -B 4000/Box -A Notes: 1.
