Description

The MAX34417 is a specialized current and voltage monitor used to determine power consumption of portable systems. The device has a very wide dynamic range (20,000:1) that allows for the accurate measurement of power in such systems. 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 and then multiplies those values to obtain a power value it then accumulates. Upon a command from the host, the device transfers the accumulated power samples, as well as 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. Watch video: Introducing the MAX34417 Evaluation KitApplicationsServersSmartphonesTabletsUltra Notebooks
