PAC1953T-E/J6CX

Current Regulation/Management Overview

The PAC1953T-E/J6CX is a three-channel power monitor manufactured by Microchip Technology, designed for high-side current and voltage sensing. It operates within a supply voltage range of 2.7 V to 5.5 V and features an operating supply current of 395 uA. The device provides measurement accuracy of 1% and functions reliably across a temperature range from -40°C to +125°C. Packaged in a compact WLCSP-16 format, it supports surface mount installation.

Current Regulation/Management Feature Summary

• Supports high-side sensing for three independent channels
• Integrates accumulator functionality for energy monitoring
• Delivers 1% measurement accuracy for precise data acquisition

Current Regulation/Management Applications

• Battery management systems requiring multi-channel monitoring
• Industrial equipment with high-side load protection needs
• Portable devices utilizing low-power consumption architectures

Current Regulation/Management Procurement Notes

Verify the specific suffix J6CX corresponds to the WLCSP-16 package configuration. Confirm that the E grade meets the required industrial temperature range specifications for your application environment. Ensure compatibility with the host system's I2C interface requirements before finalizing procurement decisions.

Current Regulation/Management Selection Notes

Select this component when three-channel high-side monitoring is required alongside accumulator capabilities. Consider the WLCSP-16 footprint constraints during PCB layout planning. Evaluate the 395 uA quiescent current against total system power budgets to ensure efficient operation in battery-powered scenarios.

Current Regulation/Management Part Context

This part belongs to the PAC195x series of multi-channel power monitors. It shares architectural similarities with other members like the PAC1954 but offers three channels instead of four. The family focuses on providing accurate power measurement with minimal external component requirements.

Current Regulation/Management Replacement Considerations

The PAC1954T-E/J6CX serves as a compatible alternative offering four channels instead of three. Verify pinout compatibility and software register mapping differences between the three-channel and four-channel variants before substitution.
