Analog Devices / Maxim Integrated MAX34417 SMBus Four-Channel Power Accumulator

Analog Devices MAX34417 SMBus Four-Channel Power Accumulator is a specialized current and voltage monitor used to determine the power consumption of portable systems. The MAX34417 has a very wide 20,000:1 dynamic range for accurate measurement of power. The device is configured and monitored with a standard I2C/SMBus serial interface and the unidirectional current sensor offers precision high-side operation.

The device automatically collects the current-sense and voltage samples and then multiplies those values to obtain a power value it accumulates. Upon a command from the host, the Analog Devices MAX34417 transfers the accumulated power samples, and the accumulation count, to a set of registers accessible by the host. This transfer occurs without missing a sample and allows the host to retrieve the data not in real-time but at any time interval.
