OH9253 Omnipolar Micropower Hall Switch datasheet
Product description
OH9253 Hall-effect sensor is a temperature stable, stress-resistant switch，including the following items on a single silicon chip: voltage regulator, Hall voltage generator, small-signal amplifier, chopper stabilization, Schmitt trigger, open-drain output. Advanced CMOS wafer fabrication processing is used to take advantage of low-voltage requirements, component matching, very low input-offset errors, and small component geometries.
Features
- CMOS Hall IC Technology
- Solid-State Reliability much better than a reed switch
- Omnipolar output switches with the absolute value of North or South pole from the magnet
- Low power consumption (2.6mA)
- High Sensitivity for reed switch replacement
- ESD HBM ±4KV Min
- COST competitive
Applications
- Solid-state switch
- Lid close sensor for power supply devices
- Magnet proximity sensor for reed switch replacement
- Safety Key Revolution counter
- Speed sensor
- Position Sensor
- Rotation Sensor
