General Description:
The OH921 is a Hall-effect latch designed in mixed signal CMOS technology.
It is quite suitable for use in 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 is directly drivable by the output.
