Computing Platform Support

• Windows^®10 Driver

• Linux Driver

- 16 bit resolution for voltage measurements,

14 bits are used for power calculations

• Real Time Auto-Calibration of Offset and Gain

Errors for Voltage and Current, No User

Description

The PAC1932/3/4 are 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

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.

• 2.7V to 5.5V Supply Operation

- 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 (1Mb/S)

The PAC1932/3/4 device family uses real time

calibration to minimize offset and gain errors. No input

filters are required for this device.

• SMBus Address – 16 Options, set with Resistor

• No Input Filters Required

• ALERT Features that can be Enabled:

- ALERT on accumulator overflow

- ALERT on Conversion Complete

• 4x4x0.5 mm UQFN Package

• 2.225x2.17 mm WLCSP Package

- WLCSP available for PAC1934 only

- Contact Marketing for other options
