2-Wire Hall Sensor from Allegro MicroSystems
Allegro MicroSystems Inc.

The A1354 from Allegro MicroSystems Inc., Worcester, MA, is a programmable 2-wire Hall effect linear sensor with a PWM output targeted at automotive and industrial markets. The device includes a voltage regulator and produces a PWM signal proportional to an applied magnetic field. The BiCMOS monolithic circuit inside the device integrates a Hall element, precision temperature-compensating circuitry to reduce intrinsic sensitivity and offset drift of the Hall element, a small-signal high-gain amplifier, proprietary dynamic offset cancellation circuits, and PWM conversion circuitry.
