The APS12202 and APS12212 Hall effect latches are suitable for operation over a wide temperature range (up to 150°C). Superior high temperature performance is achieved through dynamic offset cancellation, which reduces residual offset voltages typically caused by overmolding, temperature dependence and thermal stresses in the device package. The two devices are identical except for the magnetic switch point.

The APS12202 and APS12212 contain on a single silicon chip a voltage regulator, Hall voltage generator, small signal amplifier, chopper stabilization, Schmitt trigger and a short circuit protected open drain output that sinks up to 25mA. A strong enough negative magnetic field is required to turn the output on. A strong enough positive magnetic field is required to turn the output off. The on-board regulator allows them to operate with supply voltages from 3V to 24V.

There are two package styles available that provide a magnetically optimized package for most applications. The LH type is a small SOT23W low profile surface mount package and the UA type is a 3-pin SIP for through-hole mounting. Both packages are lead (Pb) free with 100% tin leadframe plating.
