PAC1933T-I/J6CX

Current Regulation/Management Overview

The PAC1933T-I/J6CX is a four-channel DC power monitor manufactured by Microchip Technology. It operates within an input voltage range of 2.7 V to 5.5 V and draws a typical operating supply current of 585 uA. The device provides high-side sensing with 1% accuracy across a temperature range of -40°C to +85°C. Packaged in a WLCSP-16 format, it integrates real-time calibration to minimize offset and gain errors without requiring external input filters.

Current Regulation/Management Feature Summary

• Four-channel high-side power and energy monitoring capability
• Integrated 28-bit on-chip accumulator for energy measurement
• Real-time automatic calibration for offset and gain error reduction
• Supports SMBus 3.0 and I2C Fast Mode+ communication protocols

Current Regulation/Management Applications

• Battery-powered portable devices requiring precise energy tracking
• Industrial systems utilizing multi-rail power distribution
• Embedded controllers needing cumulative power data retrieval
• High-side current sensing in low-voltage digital circuits

Current Regulation/Management Procurement Notes

Verify the specific suffix J6CX corresponds to the WLCSP-16 package variant when sourcing. Confirm that the industrial temperature grade (-40°C to +85°C) aligns with your operational environment requirements. Ensure compatibility with SMBus or I2C host interfaces before integration. Check for any recent product change notifications regarding pinout or electrical specifications.

Current Regulation/Management Selection Notes

Select this component when four independent high-side channels are required within a compact footprint. The integrated accumulator simplifies firmware by handling energy accumulation internally. Consider the 585 uA supply current impact on total system power budget. Verify that the 1% accuracy meets the precision requirements of the monitored rails compared to lower-cost alternatives.

Current Regulation/Management Part Context

This part belongs to the PAC1933 series of power monitors from Microchip Technology. It shares architectural similarities with the PAC1932 (two-channel) and PAC1934 (four-channel) variants. The series focuses on providing accurate power and energy monitoring through integrated analog-to-digital conversion and digital signal processing capabilities.

Current Regulation/Management Replacement Considerations

PAC1932T-I/J6CX offers two channels instead of four. PAC1934T-E/J6CX provides four channels but supports extended temperature ranges up to +125°C. PAC1954T-E/J6CX also features four channels with high or low-side sensing options.
