Overview

3197 PROTECTED, HIGH-TEMPERATURE, OPEN-COLLECTOR HALL-EFFECT LATCH These open-collector Hall-effect latches are capable of sensing magnetic fields while using an unprotected power supply.
The A3197LLT and A3197LU can provide position and speed information by providing a digital output for magnetic fields that exceed their predefined switch points.
These devices operate down to zero speed and have switch points that are designed to be extremely stable over a wide operating temperature and voltage range.
The latching characteristics make them ideal for use in pulse counting applications when used with a multi-pole ring magnet.
Thermal and output short-circuit protection allow an increased wir...
