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
