Allegro MicroSystems position sensor ICs
Allegro MicroSystems has developed a line of fully integrated Hall-effect digital position sensor ICs that detect changes in magnetic flux density, allowing them to distinguish movement and position. The contactless sensing solutions require few external components and can withstand the hostile operating conditions of automotive applications.
The product’s 4x chopper-stabilisation for offset cancellation provides enhanced switch point stability that increases accuracy in measuring motor speed or duty cycle, as well as good jitter performance. The device also features low-voltage (3 V) operation and low ICC for more power-efficient devices.
The products are designed to survive harsh automotive transient conditions, including double battery and 40 V load dump, without a limiting series resistor, which eliminates the need for external components and prevents transient voltage field failures.
