- Designed specifically for lithium-ion battery management systems
- Operates as an off-line controller for power supply integration
Applications
- Lithium-ion battery chargers
- Embedded electronics power management
- Industrial equipment battery systems
Procurement Notes
Verify the specific suffix AR-16.8 to confirm the 16.8V output configuration, as other variants like ADP3810AR-12.6 exist with different voltage settings. Ensure the package matches the 8-SOIC specification. Confirm manufacturer origin is Analog Devices Inc. to avoid counterfeit components. Check datasheet revisions for any pinout or electrical characteristic updates before finalizing procurement.
Selection Notes
Select this part when a fixed 16.8V secondary side control is required for Li-ion batteries. Compare against the ADP3810AR-12.6 if a lower voltage threshold is needed. Consider the SOIC-8 footprint constraints during PCB layout. Verify compatibility with the intended off-line power supply topology. Ensure thermal management supports the package type for the expected operating environment.
Part Context
This component belongs to the ADP3810 family of secondary side battery charger controllers from Analog Devices. The family includes variants such as the ADP3810AR-12.6, which targets different voltage requirements. These devices are engineered for high-precision charging control in off-line applications, distinguishing them from primary side controllers by their placement on the secondary circuit.
Replacement Considerations
The ADP3810AR-12.6 is a related variant within the same family but features a different output voltage setting. Direct substitution requires verifying that the system design accommodates the voltage difference. No other direct public substitutes are confirmed in the provided documentation.
