A1146 - Ultrasensitive Two-Wire Chopper-Stabilized Unipolar Hall Effect Switches

The A1145 and A1146 devices are two-wire, unipolar, Hall effect switches that are factory-programmed at end-of-line to optimize ultrasensitive magnetic switchpoint accuracy. These devices use a high frequency chopper-stabilization technique, produced using the Allegro advanced BiCMOS wafer fabricati.

A1146 Features

* ▪ Chopper stabilization ▫ Low switchpoint drift over operating temperature range ▫ Low sensitivity to stress ▪ Factory programmed at end-of-line for optimized switchpoints ▪ On-chip protection ▫ Supply transient protection ▫ Reverse-battery protection ▫ On-board voltage regulator ▫ 3.5 to 24 V opera
