MAX34407EWE+, SMBus, 4-Channel, Wide Dynamic Range Power Accumulator

Analog Devices' MAX34407EWE+ power accumulator enables code optimization to minimize power consumption in portable platforms

 Image of Analog Devices' MAX34407EWE+ Power AccumulatorAnalog Devices' MAX34407 is a voltage and current monitor that is specialized for determining power consumption. This device has a wide dynamic range that allows it to accurately measure power in systems that consume small to large amounts of power. The device is configured with a standard I2C/SMBus serial interface, as well as it being monitored. 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.
