MAX34407
SMBus 4-Channel Wide Dynamic Range Power Accumulator
Optimize Code Execution for Maximum Run Time in Mobile Applications

MyMaxim SubscriptionsProduct Details
The MAX34407 is a current and voltage monitor that is specialized for determining power consumption. The device has a wide dynamic range to allow it to accurately measure power in systems that consume small to large amounts of power. The device is configured and monitored with a standard I2C/SMBus serial interface. The unidirectional current sensor offers precision high-side operation with a low full-scale sense voltage. The device automatically collects the current-sense and voltage samples. The samples are then multiplied to obtain a power value and the power values are then accumulated. Upon a command from the host, the device transfers the accumulated power samples as well as the accumulation count to a set of registers that the host can access. This transfer occurs without missing a sample and allows the host to retrieve the data not in real time, but at any time interval.
