A1143, A1140 Datasheet - Allegro

A1143 - Sensitive Two-Wire Chopper-Stabilized Unipolar Hall Effect Switches

TheA1140, A1142, andA1143 devices are sensitive, two-wire, unipolar, Hall effect switches that are factory-programmed at end-of-line to optimize magnetic switchpoint accuracy. These devices use a high frequency chopper-stabilization technique, produced using the Allegro advanced BiCMOS wafer fabrica

A1143 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
