PAC1943T-E/J6CX

Current Regulation/Management Overview

The PAC1943T-E/J6CX is a three-channel power monitor with an accumulator, manufactured by Microchip Technology. It supports high-side sensing and operates within a supply voltage range of 2.7 V to 5.5 V. The device features 1% accuracy and consumes 395 uA of operating current. It is housed in a WLCSP-16 package (2.23x2.17 mm) and functions across a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Provides simultaneous monitoring of three independent channels for comprehensive power analysis
• Integrates an accumulator function to track total energy consumption over time
• Supports high-side current sensing configurations for flexible circuit integration

Current Regulation/Management Applications

• Battery management systems requiring precise energy tracking
• Portable electronic devices with multi-rail power architectures
• Industrial equipment needing high-accuracy power monitoring

Current Regulation/Management Procurement Notes

Verify the specific suffix J6CX corresponds to the WLCSP-16 package variant when sourcing. Confirm RoHS compliance status through official manufacturer documentation prior to final procurement decisions. Ensure compatibility with existing PCB footprints designed for this specific package dimensions.

Current Regulation/Management Selection Notes

Select this component when three-channel monitoring with accumulation is required in a minimal footprint. Compare against PAC1942T for dual-channel needs or PAC1953T for similar specifications. Validate that the 1% accuracy meets system requirements and that the 395 uA quiescent current fits low-power design constraints.

Current Regulation/Management Part Context

This part belongs to the PAC194x series of power monitors from Microchip Technology. It shares core architecture with the PAC1942T but adds a third channel. The series is designed for applications requiring accurate DC power measurement and energy accumulation in compact form factors.

Current Regulation/Management Replacement Considerations

PAC1942T-1E/J6CX offers dual-channel functionality. PAC1953T-E/J6CX provides equivalent three-channel performance with identical package and electrical characteristics.
