Description:

Two Wire Hall-Effect Latch

Features

* ▪ AEC-Q100 automotive qualified ▪ 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 to 24

Applications

* because they require one less wire for operation versus the more traditional open-collector output switches. Additionally, the system designer inherently gains diagnostics because there is always output current flowing, which should be in either of two narrow ranges. Any current level not within the
