ARG81403 Datasheet (Allegro)

ARG81403, Automotive PMIC

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.

The output of the pre-regulator supplies two 5 V / 100 mA trac
