PAC1954T-E/J6CX

Current Regulation/Management Overview

The PAC1954T-E/J6CX is a four-channel DC power monitor manufactured by Microchip Technology, housed in a WLCSP-16 package. It supports high-side sensing with an input voltage range of 1.62 V to 32 V and operates on a supply voltage between 2.7 V and 5.5 V. The device features 1% accuracy and includes an accumulator for energy monitoring. It functions within a temperature range of -40°C to +125°C while consuming 395 µA of operating current.

Current Regulation/Management Feature Summary

• Provides four independent channels for simultaneous DC power monitoring
• Integrates an accumulator function for cumulative energy measurement
• Supports high-side current sensing configurations
• Operates reliably across extended industrial temperature ranges

Current Regulation/Management Applications

• Battery management systems requiring precise energy tracking
• Industrial equipment power distribution monitoring
• Automotive electronics power supervision
• Telecommunications infrastructure power regulation

Current Regulation/Management Procurement Notes

Verify the specific suffix J6CX corresponds to the WLCSP-16 packaging configuration. Confirm that the E grade rating meets the required -40°C to +125°C operational temperature specifications for your application environment. Ensure compatibility with the 32V maximum input voltage limit before integration into the circuit design.

Current Regulation/Management Selection Notes

Select this component when four-channel monitoring with integrated accumulation is required. The high-side sensing capability simplifies layout compared to low-side alternatives. The wide input voltage range accommodates various bus architectures. Consider the WLCSP-16 package size constraints during PCB footprint design to ensure adequate thermal dissipation and mechanical stability.

Current Regulation/Management Part Context

This part belongs to the PAC1954 series of power monitors from Microchip Technology. It is designed for applications needing multi-channel DC power analysis. The series offers solutions for energy metering and system protection. The WLCSP-16 package provides a compact form factor suitable for space-constrained designs.

Current Regulation/Management Replacement Considerations

The PAC1934T-I/J6CX serves as a related alternative but lacks the accumulator feature and has a lower maximum input voltage of 5.5 V. Verify functional requirements against these differences before substitution.
