PAC1951T-2E/J6CX

Current Regulation/Management Overview

The PAC1951T-2E/J6CX is a single-channel power monitor from Microchip Technology, designed for high-side sensing applications with a maximum voltage rating of 32V. It operates on a supply voltage range of 2.7V to 5.5V and features an accuracy of 1%. The device consumes 395uA of operating current and functions within a temperature range of -40°C to +125°C. Packaged in a 16-WLCSP (WFBGA) format measuring 2.2x2.2mm, it supports surface mount installation.

Current Regulation/Management Feature Summary

• Integrates accumulator functionality for cumulative energy monitoring
• Supports high-side current and power sensing configurations
• Provides precise measurement capabilities with specified accuracy levels

Current Regulation/Management Applications

• Battery management systems requiring energy accumulation tracking
• Portable electronics with limited power budgets
• Industrial equipment monitoring high-side loads

Current Regulation/Management Procurement Notes

Verify the specific suffix J6CX corresponds to the WLCSP-16 package variant when ordering. Confirm that the high-side sensing configuration aligns with your circuit topology, as low-side variants exist within the same family. Ensure thermal management meets the specified operating temperature range during integration.

Current Regulation/Management Selection Notes

Select this component when a single-channel monitor with accumulator support is required for high-side applications up to 32V. Compare against PAC1951T-1E/J6CX if low-side sensing is preferred instead. Consider the 16-WLCSP footprint constraints and verify compatibility with existing PCB layout dimensions before finalizing the design.

Current Regulation/Management Part Context

This part belongs to the PAC1951 series of power monitors, which are optimized for accurate current and voltage measurements. The T-2E designation indicates the specific channel count and sensing orientation. It is categorized under PMIC Current & Power Monitors & Regulators, serving as a critical component for system health monitoring.

Current Regulation/Management Replacement Considerations

PAC1951T-1E/J6CX offers identical specifications but utilizes low-side sensing instead of high-side. PAC1941T-2E/J6CX provides similar monitoring features but is rated for lower voltages up to 9V. Verify pinout and functional equivalence before substituting.
