General Description

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 ENABLE pins and both switches are protected with current-limiting circuitry.

Overview

A6850 Dual Channel Switch Interface IC.

Key Features

  • 4.75 to 26.5 V operation.
  • Low VIN-to-VOUT voltage drop.
  • 1/10 current sense feedback.
  • Survive short-to-battery and short-to-ground faults.
  • Survive 40 V load dump.
  • >4 kV ESD rating on the output pins, >2 kV on all other pins.
  • Output current limiting.
  • Low operating and Sleep mode currents.
  • Integrates with Allegro A114x and A118x Hall effect two-wire sensor ICs.
