The AH9251 is a medium sensitivity micropower Omnipolar hall-effect switch ICs, specifically designed for portable and battery powered consumer equipment, to home appliances and industrial applications.
Based on High/Medium sensitivity hall effect plates and chopper stabilized architecture, the AH9251 provides a reliable solution over the whole operating range.
The high and Medium sensitivity hall effect switches have been optimized to operate over the supply range of 2.5V to 5.5V and use a micropower sleep function to give an average supply current of only 8uA.
AH9251 has push pull output for flexibility.They are small low profile industry standard SC59 and TO92S packages.
