PAC1941T-1E/J6CX

Current Regulation/Management Overview

The PAC1941T-1E/J6CX is a single-channel DC power monitor manufactured by Microchip Technology, designed for high-side current and voltage sensing applications. It operates within an input voltage range of 2.7 V to 5.5 V and features a supply current of 395 uA. The device provides measurement accuracy of 1% and functions across a temperature range from -40°C to +125°C. Packaged in a compact 16-WLCSP (2.23x2.17 mm) format, it integrates accumulation capabilities for energy monitoring.

Current Regulation/Management Feature Summary

• Integrates high-side sensing capability for precise current and voltage monitoring
• Includes internal accumulator for cumulative energy measurement
• Supports wide operating temperature range suitable for industrial environments

Current Regulation/Management Applications

• Battery management systems requiring accurate charge monitoring
• Portable electronic devices with strict power constraints
• Industrial equipment needing isolated power path supervision

Current Regulation/Management Procurement Notes

Verify the specific suffix J6CX corresponds to the WLCSP-16 package variant when sourcing. Confirm that the E-grade designation aligns with the required -40°C to +125°C industrial temperature rating. Ensure compatibility with the 2.7 V to 5.5 V supply rail before integration into the design.

Current Regulation/Management Selection Notes

Select this component when a single-channel solution with high-side sensing is required. The 1% accuracy meets standard monitoring needs without excessive cost. Consider the 16-WLCSP package size if board space is limited compared to larger QFN or SOIC alternatives.

Current Regulation/Management Part Context

This part belongs to the PAC1941 family of power monitors. It shares core architecture with other variants but differs in channel count and sensing configuration. The T-1E suffix indicates a specific temperature grade and packaging option within the broader product line.

Current Regulation/Management Replacement Considerations

PAC1941T-2E/J6CX offers similar specifications but may differ in low-side sensing support. PAC1951T-1E/J6CX provides multi-channel capabilities. Verify pinout and register compatibility before substituting.
