ADP3810AR-12.6

Overview

The ADP3810AR-12.6 is a secondary-side, off-line battery charger controller designed for lithium-ion and lithium-polymer battery packs. It supports a nominal battery voltage of 12.6 V, corresponding to four series-connected Li-Ion cells. The device integrates programmable current limit and battery voltage limit functions to provide constant current and constant voltage charging profiles. It is intended for use in embedded electronics and industrial equipment applications requiring precise battery management.

Feature Summary

• Integrates programmable current limit with battery voltage limit for controlled charging
• Designed for secondary-side, off-line battery charger topologies
• Supports constant current and constant voltage charging modes

Applications

• Embedded electronics battery charging systems
• Industrial equipment power management
• Lithium-ion battery pack protection and control

Procurement Notes

Verify the exact suffix RL7 or other packaging variants when ordering, as availability may vary by distributor. Confirm that the 12.6V rating matches your specific four-cell lithium-ion configuration. Check for obsolescence status or lifecycle notices from Analog Devices prior to final design-in decisions.

Selection Notes

Select this component when designing off-line chargers for four-series lithium-ion batteries requiring integrated voltage limiting. Ensure the application topology supports secondary-side control. Compare against the ADP3811 if external resistor programming for variable voltages is preferred over fixed internal options.

Part Context

The ADP3810 family offers four fixed voltage options (4.2V, 8.4V, 12.6V, 16.8V) corresponding to one to four cell configurations. The ADP3810AR-12.6 specifically targets the 12.6V (four-cell) market segment. It complements the ADP3811, which allows flexible voltage setting via external resistors.

Replacement Considerations

The ADP3811 serves as a flexible alternative where adjustable voltage settings are required instead of fixed 12.6V. Verify pin compatibility and control loop stability when substituting between fixed-voltage and programmable variants within the same family.
