Power Management - Specialized Procurement Notes

Verify component authenticity through authorized Analog Devices distributors or certified partners. Confirm the specific suffix 'T' indicates tape-and-reel packaging if required by assembly processes. Check for recent discontinuance notifications as this part may have limited availability. Ensure the 36-pin WLP footprint matches your PCB design constraints before ordering.

Power Management - Specialized Selection Notes

Select this component when a compact solution combining PLC connectivity and battery management is required. The integrated fuel gauge and protector simplify system design by reducing external component count. Consider the 380µA supply current for low-power standby requirements. Verify that the 2.8V to 5.5V input range aligns with your system's power architecture.
