A6850 Dual-Channel Switch Interface

The Allegro™ A6850 is designed to interface between a microprocessor and a pair of two-wire Hall effect sensor ICs. The A6850 uses protected high-side low resistance DMOS MOSFETs to switch the supply voltage to the two Hall effect devices. Each switch can be controlled independently via individual E.
