Hall-effect digital position sensor ICs detect changes in magnetic flux density, allowing them to distinguish movement and position. These contactless sensing solutions require few external components and can withstand the hostile operating conditions of automotive applications.
Specific advantages of Allegro’s solutions include:
- 4x chopper-stabilization for offset cancellation provides: enhanced switch point stability that increases accuracy in measuring motor speed or duty cycle, and industry leading jitter performance that outperforms the competition
- Low voltage (3 V) operation and lower ICC for more power efficient devices
- Many standard products are designed to survive harsh automotive transient conditions, including double battery and 40 V load dump, without a limiting series resistor, which eliminates the need for external components and prevents transient voltage field failures
The majority of Allegro’s digital position sensing volume ships into demanding automotive applications, and has a proven quality record and dedication to continuous improvement.
Allegro offers a broad range of switching and latching solutions to cover just about any application need.
