TX1661H

The TX1661H Hall-Effect switch, produced with high voltage Bipolar technology. The Hall IC internally includes an on-chip Hall voltage generator, a voltage regulator for operation, with supply voltages of 3.8 to 80V, reverse protection diode, temperature compensation circuitry, small-signal amplifier, Schmitt trigger and an open-collector output. They are designed to respond to alternating North and South poles. While the magnetic flux density(B) is larger than operate point (Bop), the output will be turned on (Low), the output is held until the magnetic flux density(B) is lower than release point(Brp) then turn off (High).
