General Description: The OH920 is a Hall-effect latch designed in mixed
signal CMOS technology. It is quite suitable for usein automotive, industrial and
consumer applications. Superior high-temperature performance is made
possible through dynamic offset cancellation, which reduces the residual offset
voltage normally caused by device over-molding, temperature dependencies,and thermal
stress. The device integrates a voltage regulator, Hall-voltage generator, small-signal
amplifier, chopper stabilization, schmitt trigger, and open-drain output.
An on-board regulator permits operation with supply voltage from 3.5V to 20V.
