A1150

Chopper-Stabilized, Two Wire Hall-Effect Switches

Description

The , A1152, A1153, A1155, A1156, A1157, and A1158 comprise a family of two-wire, unipolar, Hall-effect switches, which are factory-trimmed to optimize magnetic switchpoint accuracy. These devices are produced on the Allegro® advanced BiCMOS wafer fabrication process, which implements a patented high frequency, 4-phase, chopper-stabilization technique. This technique achieves magnetic stability over the full operating temperature range, and eliminates offsets inherent in devices with a single Hall element that are exposed to harsh application environments.

Features and Benefits

▪ High speed, 4-phase chopper stabilization

▪ Low switchpoint drift throughout temperature range

▪ Low sensitivity to thermal and mechanical stresses

▪ On-chip protection

  ▫ Supply transient protection

  ▫ Reverse battery protection

  ▫ On-board voltage regulator

  ▫ 3.0 to 24 V operation

▪ Solid-state reliability

▪ Robust EMC and ESD performance

▪ Industry leading ISO 7637-2 performance through use of proprietary, 40-V clamping structures
