PAC1954T-E/4MX

Current Regulation/Management Overview

The PAC1954T-E/4MX is a four-channel power monitor manufactured by Microchip Technology, designed for high-side sensing applications with an integrated accumulator. It operates within a supply voltage range of 2.7 V to 5.5 V and draws a typical operating current of 395 uA. The device provides measurement accuracy of 1% and functions reliably across an extended temperature range from -40°C to +125°C. Packaged in a WLCSP-16 format suitable for surface mount technology, it supports I2C communication interfaces for system integration.

Current Regulation/Management Feature Summary

• Four independent channels enable simultaneous monitoring of multiple power rails
• Integrated accumulator function allows for cumulative energy tracking over time
• High-side sensing capability simplifies circuit design without requiring low-side placement

Current Regulation/Management Applications

• Battery management systems requiring precise energy accumulation
• Portable electronics with multi-rail power distribution
• Industrial equipment monitoring critical power consumption metrics

Current Regulation/Management Procurement Notes

Verify the specific suffix E/4MX against official Microchip documentation to confirm package type and temperature grade. Ensure compatibility with existing PCB footprints for WLCSP-16 components. Cross-reference datasheet revisions to validate electrical characteristics match project requirements before finalizing procurement orders.

Current Regulation/Management Selection Notes

Select this component when four-channel monitoring with energy accumulation is required in a compact form factor. Compare against PAC1942 variants if fewer channels suffice or different packaging is preferred. Confirm interface compatibility with host microcontrollers supporting standard I2C protocols for seamless data acquisition.

Current Regulation/Management Part Context

This part belongs to the PAC195x family of multi-channel power monitors from Microchip Technology. It shares core architectural features with other members like PAC1954T-E/J6CX but differs in packaging configuration. The family targets applications needing detailed power analysis in space-constrained environments.

Current Regulation/Management Replacement Considerations

PAC1954T-E/J6CX serves as a functional alternative within the same product family, offering identical electrical performance but utilizing a different package style.
