Latching Switch Hall-Effect IC Basics

There are four general categories of Hall-effect IC devices that provide a digital output: unipolar switches, bipolar switches, omnipolar switches, and latches. Latching Hall-effect sensor ICs, often referred to as "latches," are digital output Hall-effect switches that latch output states.
