PAC1720-1-AIA-TR

Current Regulation/Management Overview

The PAC1720-1-AIA-TR is a dual-channel, high-side current and power monitor manufactured by Microchip Technology. It features an I²C-compatible interface for digital communication and operates within a supply voltage range of 3 V to 5.5 V. The device provides accurate measurement of current and power in applications requiring precise energy monitoring. It is housed in a compact 10-lead DFN package measuring 2.4 mm x 1.7 mm with a height of 0.9 mm. The component supports a minimum common-mode rejection ratio (CMRR) of 80 dB and functions reliably across an operating temperature range from -40 °C to +85 °C.

Current Regulation/Management Procurement Notes

Verify the specific suffix AIA against official Microchip documentation to confirm pinout and package configuration. Ensure compatibility with the target I²C bus voltage levels before integration. Confirm that the operating temperature range meets the environmental requirements of the final application. Cross-reference the manufacturer part number with authorized distributors to avoid counterfeit components.

Current Regulation/Management Selection Notes

Select this component when dual-channel monitoring is required on the high side of a circuit. Consider the 80 dB CMRR specification for environments with significant electrical noise. Evaluate the 10-DFN package dimensions against available PCB real estate constraints. Verify that the 3 V to 5.5 V supply range aligns with the system's power architecture.
