The SC1945 Hall-Effect switch, produced with ultra high voltage Bipolar technology, has been designed specifically for automotive and industrial applications. New considerations are given not only to protect the IC from the high voltage transients, but also achieving a high degree of noise immunity.
Each device includes a voltage regulator for operation with supply voltages of 3.8 to 60V volts, quadratic Hall-voltage generator, temperature compensation circuitry, small-signal amplifier, Schmitt trigger, and an output driver to sink up to 60mA. Internal integrated output filter can improve the EMC capability.
The device is available in a 3-pin SIP package (UA) and is lead (Pb) free, with 100% matte tin leadframe plating.
