Procurement Notes
Verify the complete part number including suffixes such as RL7 against official Analog Devices documentation to ensure correct packaging and variant specifications. Confirm that the SOT-23-6 package matches your PCB footprint requirements. Cross-reference the 4.2V output specification with your battery cell datasheet to ensure compatibility. Ensure sourcing channels provide original manufacturer components to avoid counterfeit risks associated with power management ICs.
Selection Notes
Select this component when designing circuits for single-cell lithium-ion batteries requiring a fixed 4.2V charge termination voltage. The SOT-23-6 package is suitable for applications with limited board space. Consider thermal performance and input voltage ranges compatible with the system's power source. Verify that the integrated power management features meet the specific safety and efficiency requirements of the target application without external discrete components.
Part Context
This component belongs to the ADP3820 series from Analog Devices, focused on power management for battery-operated devices. The series includes variants with different charge voltages, such as the ADP3820ART-4.1. These ICs are engineered to simplify battery charging design by integrating necessary control logic and power stages into a small form factor, reducing bill-of-materials complexity for portable electronics manufacturers.
Replacement Considerations
Check Analog Devices documentation for direct pin-compatible alternatives within the ADP3820 family, such as the ADP3820ART-4.1, if a different charge voltage is required. Verify electrical characteristics and package dimensions before substitution.
