AH45X
High Voltage Hall Effect Switch Family
Alfa Electronics Co. Ltd
Introduction
AH45x omnipolar Hall effect switch family, designed with Bipolar technology, is both south and north poles sensitive omnipolar Hall effect switch and includes on-chip Hall element voltage generator, a voltage regulator for operation with supply voltages of 4.5 to 60V, reverse voltage protection, temperature compensation circuitry, small-signal amplifier, Schmitt trigger and an open-collector output.
The sensor family is designed to respond to both south pole and north pole. While the magnetic flux density(B) is larger than operate point Bop, the output will be turned on with low output level. Then the output is held until the magnetic flux (B) is lower than release point Brp.
