General Description

Description

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.

Features

• Wide Operating Voltage Range from 3.5 to 24V

• Symmetrical Switch Points

• Chopper-stabilized Amplifier Stage

• Superior Temperature Stability

• Compact Size

• Built-in Pull-up Resistor

• ESD Rating: 3500V (Human Body Model)
