Description

The PAC1931/2/3/4 are one, two, three and

four-channel power and energy monitoring devices. A

high-voltage multiplexer sequentially connects the

inputs to a bus voltage monitor and current sense

amplifier that feed high-resolution ADCs. Digital

circuitry performs power calculations and energy

accumulation.

• On-Chip Accumulation of 28-bit Power Results for

Energy Measurement

- 48-bit power accumulator register for

recording accumulated power data

- 24-bit Accumulator Count

User programmable sampling rates of 8, 64,

256 and 1024 samples per second

This enables energy monitoring with integration

periods from 1 ms up to 36 hours or longer. Bus

voltage, sense resistor voltage and accumulated

proportional power are stored in registers for retrieval

by the system master or Embedded Controller.

- 17 minutes of power data accumulation

minimum at 1024 S/s

Over 36 hours of power data accumulation

minimum at 8 S/s

• 2.7V to 5.5V Supply Operation

The sampling rate and energy integration period can be

controlled over SMBus or I²C. Active channel selection,

one-shot measurements and other controls are also

configurable by SMBus or I²C.

- Separate V_DDI/O pin for digital I/O

- 1.62-5.5V capable SMBus and digital I/O

SMBus 3.0 and I²C Fast Mode Plus (1 Mb/S)

• SMBus Address – 16 Options, set with Resistor

• No Input Filters Required

The PAC1931/2/3/4 device family uses real time

calibration to minimize offset and gain errors. No input

filters are required for this device.

• ALERT Features that can be Enabled:

- ALERT on accumulator overflow

- ALERT on Conversion Complete

• 4 × 4 × 0.5 mm UQFN Package

• 2.225 × 2.17 mm WLCSP Package
