MAX34427/MAX34417 SMBus Dual/Quad Range Power Accumulators

Analog Devices' MAX34427 and MAX34417 devices are configured and monitored with a standard I2C/SMBus serial interface

Image of Analog Devices' MAX34427/MAX34417 SMBus Dual/Quad Range Power AccumulatorsADI's MAX34427 and MAX34417 power accumulators are specialized current, voltage, and power monitors used to determine the power consumption of systems. Both devices have a very wide dynamic range (20,000:1) that allows for the accurate measurement of power in such systems. The devices are 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 MAX34427 shield evaluation kit (MAX34427SHLD#) provides the hardware and software graphical user interface (GUI) necessary to evaluate the MAX34427, an SMBus two-channel, high dynamic range current, voltage, and power accumulator. It is a fully assembled and tested PCB. The shield operates from a single supply (either from a USB or an 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 and a micro-USB cable.

The MAX34417 evaluation kit (MAX34417EVKIT#) provides the hardware and software GUI necessary to evaluate the MAX34417 SMBus four-channel, high dynamic range power accumulator. The EV Kit includes a MAX34417ENE+ installed EV board and a micro-USB cable to communicate with a PC.

Features

  • Small multichannel power accumulator and WLP with no orphan pads helps space-constrained applications
  • Low sense voltage (down to 5 μV) enables smaller, less expensive resistors
  • Highly accurate power measurement with <3.5% error at VSENSE = 50 µV
Applications
  • Servers
  • Smartphones
  • Tablets
  • Ultra-notebooks
