IR3725 Overview
The IR3725 is a highly configurable power monitor IC that uses proprietary digital technology to measure a 12V rail current, its voltage, or its average power over a user specified time interval. Configuration and result reporting are managed through a serial digital interface. The current is measured as a voltage across a shunt resistance, an input inductor, or a copper trace resistance.
