ARG82801-1 Overview
The ARG82801-1 is a power management IC that integrates a buck or buck/boost pre-regulator, four LDOs, and four floating gate drivers. The pre-regulator uses a buck or buck/boost topology to efficiently convert automotive battery voltages into a tightly regulated intermediate voltage plete with control, diagnostics, and protections. The output of the pre-regulator supplies a 3.3 V or 5.0 V selectable 350 mA linear...
