1 / 9 page AH173 INTERNAL PULL-UP HALL EFFECT LATCH FOR HIGH TEMPERATURE AH173 Rev. 4 1 of 9 FEBRUARY 2007 www.diodes.com © Diodes Incorporated Lead-free • Bipolar Hall Effect Latch Sensor • 3V to 20V DC Operation Voltage • Built-in Pull-Up Resistor • 25mA Output Sink Current • Operating Temperature: C 125 ~ C 40 ° + ° − • Lead Free Finish/RoHS Compliant for Lead Free products (Note 1) • Lead Free Package: SIP-3L, SC59-3L • Green Package: SC59-3L AH173 is a single-digital-output Hall-effect sensor with pull-up resistor 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 output driver with a pull-up resistor (Rpu). 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 operate point (Bop), the OUT pin turns on (low). If B moves toward release point (Brp), the OUT pin is latched “on” state prior to B < Brp. When B < Brp, the OUT pin goes into “off ” state. • Rotor Position Sensing • Current Switch • Encoder • RPM Detection AH 173 X X X -X Packing - 7 : -B : - A : Taping Bulk (Note 4) Ammo Box (Note 5) P: SIP-3L W: SC59-3L Package Lead-Free L : Lead Free Magnetic Characteristics A or B - G : Green (Note3) Note: 1.
