Magnetic Switch & Latch ICs

Allegro MicroSystems Magnetic Switch and Latch ICs provide excellent jitter performance for optimized motor control. The magnetic switch and latch ICs feature vertical hall technology and survive the harshest automotive voltage transients. Furthermore, the switches and latches are developed to ISO 26262 standards.

Magnetic Speed Sensor ICs

Allegro MicroSystems Magnetic Speed Sensor ICs offer a comprehensive portfolio covering the full range of speed and speed with direction sensor ICs. These products include a two- and three-wire interface, a magnetic encoder (ring magnet) and gear tooth sensing, Hall and GMR technology, and ASIL-compliant options for transmission, wheel speed, engine, e-motors, and many more encoder and gear tooth sensing applications.

A1220/A1221/A1222/A1223 Hall-Effect Sensor ICs

Allegro MicroSystems A1220/A1221/A1222/A1223 Hall-Effect Sensor ICs are stress-resistant and temperature-stable devices designed for operation over extended temperature ranges up to 150°C. These sensor ICs feature superior high-temperature performance achieved by dynamic offset cancellation that reduces the residual offset voltage caused by device overmolding, temperature dependencies, and thermal stress. The Hall-effect sensor ICs come with an onboard regulator that allows operation with supply voltages of 3V to 24V. Operating down to 3V enables the device to be used in 3V applications or with additional external resistance in series with the supply pin for more excellent protection against high-voltage transient events. Typical applications include power closures/actuators, electronic power steering, BLDC motors, and fan motors.
