The MAX34427 is a specialized current, voltage, and power monitor used to determine power consumption of 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 only in real-time, but at any time interval.

Product Detail

The MAX34427 Shield evaluation kit (EV kit) is a fully assembled and tested PCB to evaluate the MAX34427, a SMBus two-channel, high dynamic range current, voltage, and power accumulator. The Shield operates from a single supply (either from USB or external power supply). This device is accessed through an I2C serial interface provided by a MAX32625PICO board connected to a PC by a USB port.

The MAX34427 Shield EV kit provides the hardware and software graphical user interface (GUI) necessary to evaluate the MAX34427. The kit includes an installed MAX34427. It connects to the PC through a MAX32625 PICO board and a micro-USB cable.
