PAC1951 - Single/Multi-Channel Power Monitor

Download the PAC1951 datasheet PDF. This datasheet also covers the PAC1951-1 variant, as both devices belong to the same single/multi-channel power monitor family and are provided as variant models within a single manufacturer datasheet.

General Description

The PAC195X products are one, two, three and four-channel energy monitors, with bus voltage monitors and current sense amplifiers that feed high-resolution ADCs.

Key Features

  • High-Side/Low-Side Current Monitor with One, Two, Three or Four Channels: - 100 mV Full-Scale Range (FSR) for current sense voltage - Programmable FSR: -50 mv to +50 mv - 16-bit resolution for current measurements - External sense resistor sets the full-scale current range - Very low input current simplifies routing.
  • Voltage Monitor with Wide VBUS Range - 0V to 32V FSR - 16V programmable VBUS option - 16-bit resolution for voltage measurements.
