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 - Operating temperature: −40°C ~ +125°C - Package: SIP3, SOT23
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 bandgap
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 go into “ off ” state.
Applications
- Rotor position sensing - Current switch - Encoder - RPM detection
