FEATURES
DESCRIPTION
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.
The real time
voltage and current signals are multiplied, digitized, and averaged over a user selectable averaging interval providing TruePowerâ„¢ measurement of highly dynamic loads.
„ Accurate power, cu...
