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.
