PAC1933T-I/JQ

Current Regulation/Management Overview

The PAC1933T-I/JQ is a four-channel DC power monitor manufactured by Microchip Technology. It operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical operating current of 585 µA. The device provides high-side sensing with an accuracy of 1%. It supports I²C and SMBus communication interfaces and functions within a temperature range of -40°C to +85°C. The component is housed in a 16-pin UQFN package and is available in tape and reel or cut tape formats.

Current Regulation/Management Feature Summary

• Four independent channels for simultaneous DC power monitoring
• High-side current sensing capability
• Digital interface compatibility with I²C and SMBus protocols

Current Regulation/Management Applications

• Battery management systems
• Portable electronic devices
• Industrial equipment power monitoring

Current Regulation/Management Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to ensure correct packaging and temperature grade alignment. Confirm that the UQFN-16 footprint matches the target PCB design constraints. Ensure compliance with RoHS directives as indicated in manufacturer specifications before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when multi-channel DC power monitoring is required with low quiescent current consumption. The 1% accuracy specification suits applications demanding precise energy measurement. Verify that the host controller supports the necessary digital communication protocols for data retrieval from all four channels simultaneously.

Current Regulation/Management Part Context

This part belongs to the PAC1933 family of power monitors, designed for efficient energy tracking in battery-powered systems. It integrates precision amplifiers and analog-to-digital converters to measure voltage, current, and power across multiple rails without external shunt resistors in some configurations.

Current Regulation/Management Replacement Considerations

Consult Microchip datasheets for direct pin-compatible alternatives within the PAC19xx series. Verify channel count and accuracy requirements match before substituting with other manufacturers' current sensors.
