AH3781-P-A is a high-voltage, high-sensitivity hall-effect latch IC with an internal pullup resistor designed for commutation of brushless DC motors, flow meters, linear encoders and position sensors in industrial, consumer home appliance and personal care applications. For robustness and protection, the device has a Zener clamp on the supply. The output has an overcurrent limit and a Zener clamp. When the magnetic flux density (B) perpendicular to the part marking surface is larger than the operate point (BOP) the output is switched on (pulled low). The output is held latched until the magnetic flux density reverses and becomes lower than the release point (BRP). Applications include revolution per minute (RPM) measurement, contactless commutation, speed measurement and angular position sensing/indexing in consumer home appliances, office equipment and industrial applications.
- Bipolar latch operation (south pole: on, north pole: off)
- 3.0V to 28V operating voltage range
- Internally pullup resistor on the output pin
- Output overcurrent limit, good RF noise immunity
- Chopper stabilized design provides superior temperature stability
- Minimal switch point drift, enhanced immunity to stress
- Zener clamp on supply and output pins
- ESD (HBM): 6kV
- SIP-3 (ammo pack) package
- Operating temperature range from -40 to +125°C
