PAC1952T-1E/4MX

Current Regulation/Management Overview

The PAC1952T-1E/4MX is a dual-channel power monitor manufactured by Microchip Technology, designed for high-side or low-side current sensing applications. It operates within a supply voltage range of 2.7 V to 5.5 V and features an I2C interface for digital communication. The device provides 1% accuracy in power monitoring and includes an accumulator function for energy measurement. It is housed in a compact WLCSP-16 package, suitable for surface mount installation, and supports operation across a temperature range of -40°C to +125°C.

Current Regulation/Management Feature Summary

• Dual-channel power monitoring with integrated accumulator for cumulative energy measurement
• Supports both high-side and low-side current sensing configurations
• Digital output via I2C serial interface for system integration
• High accuracy performance with 1% measurement precision

Current Regulation/Management Applications

• Battery management systems requiring precise energy tracking
• Portable electronics with limited space constraints
• Industrial equipment needing multi-rail power monitoring
• Automotive subsystems operating in extended temperature ranges

Current Regulation/Management Procurement Notes

Verify the specific suffix '4MX' against official Microchip documentation to confirm the exact package type and tape/reel specifications. Ensure compatibility with your PCB footprint design for the WLCSP-16 configuration. Confirm that the I2C address settings align with your system's bus requirements before procurement.

Current Regulation/Management Selection Notes

Select this component when dual-channel monitoring with accumulation is required in a minimal footprint. Compare against single-channel alternatives if only one rail needs monitoring. Consider the WLCSP-16 package availability and soldering requirements during the design phase. Verify that the 1% accuracy meets your system's tolerance thresholds for power management.

Current Regulation/Management Part Context

This part belongs to the PAC1952 series of power monitors from Microchip Technology. The series offers various channel counts and sensing options. The PAC1952T-1E variant specifically denotes the dual-channel version with the specified package and temperature grade. Other variants may differ in channel count or packaging style.

Current Regulation/Management Replacement Considerations

Check for PAC1952T-2E/4MX if low-side sensing is preferred over high-side. Verify PAC1952T-1E/J6CX for alternative WLCSP packaging options. Consult Microchip's official substitution guide for pin-compatible alternatives with similar electrical characteristics.
