PAC1931 - Single/Multi-Channel DC Power/Energy Monitor

Download the PAC1931 datasheet PDF. This datasheet also covers the PAC1932 variant, as both devices belong to the same single/multi-channel dc power/energy monitor family and are provided as variant models within a single manufacturer datasheet.

General 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.

Key Features

  • High-Side Current Monitor with One, Two, Three or Four Channels - 100 mV full-scale range for current sense voltage,16-bit resolution - Selectable bidirectional current sense capability, -100 mV to +100 mV range, 16-bit two’s complement (signed) data format - External sense resistor sets full scale current range - Very low input current simplifies routing.
  • Wide Bus Voltage Range for Voltage Monitor - 0V to 32V input common-mode voltage - 16-bit resolution for voltage measureme.
