W83303AG

Overview

The W83303AG is an ACPI controller IC manufactured by Nuvoton Technology Corporation, housed in a 48-LQFP surface-mount package. It operates within a supply voltage range of 4.75V to 5.25V and draws a supply current of 20µA. The device functions reliably across an operating temperature range of 0°C to 70°C. Classified under Power Management - Specialized PMICs, it serves as a dedicated controller for ACPI systems.

Feature Summary

• Acts as a dedicated ACPI controller for system power management
• Designed for surface-mount installation in compact form factors
• Operates with low supply current consumption

Applications

• ACPI system controllers
• Power management integrated circuits
• General-purpose controller applications

Procurement Notes

Verify component status carefully, as the W83303AG is listed as obsolete or end-of-life with a discontinuation date around July 2026. Confirm availability through authorized distributors or secondary markets. Ensure the 48-LQFP package matches your PCB footprint requirements. Check for any specific handling precautions related to its moisture sensitivity level (MSL 3) during storage and assembly processes.

Selection Notes

Select this component only if ACPI controller functionality is required and the 48-LQFP package is compatible with the design. Consider the limited supply chain due to its obsolete status. Evaluate alternative modern PMICs if long-term production stability is critical. Verify that the 4.75V-5.25V supply range aligns with the target system's power rails.

Part Context

Nuvoton Technology Corporation, spun off from Winbond Electronics, specializes in microcontrollers, audio ICs, and power management solutions.
