Allegro MicroSystems Inc.

The A1356 from Allegro MicroSystems Inc., Worcester, MA, is a user-programmable, linear Hall-effect sensor IC with PWM output and a 2 kHz carrier frequency. Suited for use in gear detection; fork, clutch, and neutral positions in the automotive market; and in industrial applications, the device converts an analog signal from its internal Hall sensor element to a digitally encoded PWM output signal. The BiCMOS monolithic circuit inside the device integrates a Hall element, temperature compensating circuitry, a small-signal high-gain amplifier, dynamic offset cancellation circuits, and PWM conversion circuitry. Gain, quiescent duty cycle, and carrier frequency are user-programmable.
