MAX34427/MAX34417: SMBus dual/quad dynamic range power accumulators
NPI28 Oct 2022
The MAX34427/MAX34417 power accumulators are specialized current, voltage, and power monitors used to determine 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.
Both the MAX34427/MAX34417 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.
- MAX34427: SMBus Dual Channel High Dynamic Range Power Accumulator
- MAX34417: SMBus Four-Channel Very Wide Dynamic Range Power Accumulator
Key features and benefits
- Smallest multichannel power accumulator and WLP with no orphan pads helps space-constrained applications
- Lowest sense voltage (down to 5 μV) enables smaller, less expensive resistors
- Highly accurate power measurement with <3.5% error at VSENSE = 50 µV
Applications
- Consumer: Tablets, notebooks, smartphones
- Data Center: Servers
Evaluation board
- The MAX34427/MAX34417 can be evaluated with the MAX34427SHLD.
