ARG81403 - Automotive PMIC

General Description

The ARG81403 is power management IC that uses a 2.2 MHz synchronous buck pre-regulator to efficiently convert automotive battery voltages into a tightly regulated intermediate voltage, complete with control, diagnostics, and protections.

Key Features

  • Automotive AEC-Q100 qualified.
  • A2-SIL™ product.
  • device features for safety-critical systems.
  • 6 to 36 VIN operating range, 40 VIN maximum.
  • 2.2 MHz synchronous buck pre-regulator (VREG).
  • Adjustable synchronous buck regulator (1.275 V or 1.25 V typ).
  • 3.3 V (3V3) and 5 V (V5) internal LDO regulators with foldback short-circuit protection.
  • 5 V (V5P1 and V5P2) internal tracking LDO regulator with foldback short-circuit and short-to.
