Device Overview

Summary

The PAC1932 is a dual power monitor and energy monitor that reports on bus voltage and sense voltage 16-bits of resolution.  Power is reported as a simultaneous product of two 16-bit independent bus and sense voltages.  All registers are accessible through I2C / SMBus including an 8 sample average for reading stability.

Additional Features
  • Dual High-Side Current Sensor
    • 100 mV full scale range for current sense voltage
    • Selectable bidirectional measurement capability
    • External sense resistor sets full scale current range
    • 0 to 32V Input Common-Mode Voltage
    • 1% Power Measurement Accuracy Over a Wide Dynamic Range
    • On-Chip Accumulation of 28-bit Power Results for Energy Measurement
    • 48-bit power accumulator register
    • Sampling rates of 8, 64, 256, and 1024 samples per second
    • At least 17 minutes of power accumulation data at 1024 samples per second
  • 2.7V to 5.5V Supply Operation
    • Separate VDD for I/O pin
    • 1.62-5.5 capable SMBus and digital I/O
    • SMBus 3.0 and I2C Fast Mode Plus
