A31015 Linear Hall-Effect Sensor

Allegro MicroSystems A31015 Linear Hall-Effect Sensor is a nanopower, ratiometric linear Hall-effect sensor IC designed specifically to maximize battery life in portable and space-constrained applications. Unlike traditional linear sensors that consume constant power, the A31015 features a dedicated active-high enable (EN) pin, allowing system microcontrollers to duty-cycle the A31015. This power-gating capability reduces average power consumption to less than 1µW (at 10Hz cycling), while the ultra-low-leakage sleep mode consumes less than 1nA.
