3197 Datasheet (Allegro MicroSystems) - OPEN-COLLECTOR HALL-EFFECT LATCH

3197, OPEN-COLLECTOR HALL-EFFECT LATCH

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 voltag
