ADP3810AR-8.4

Overview

The ADP3810AR-8.4 is a secondary side, off-line battery charger controller manufactured by Analog Devices Inc. It combines programmable current limit with battery voltage limit to provide constant current and constant voltage charging profiles. Designed for lithium-ion or lithium-polymer batteries, this component supports a maximum pack voltage of 8.4V, corresponding to two series-connected cells. The device integrates over-current and over-voltage protection mechanisms to ensure safe operation during the charging cycle.

Feature Summary

• Integrates programmable current limit with battery voltage limit for precise charge control
• Provides constant current and constant voltage charging modes
• Includes built-in over-current and over-voltage protection features

Applications

• Charging systems for 2-series lithium-ion battery packs
• Charging systems for 2-series lithium-polymer battery packs
• Off-line battery charger controllers requiring 8.4V max pack voltage

Procurement Notes

Verify the specific suffix AR-8.4 to confirm the 8.4V battery pack voltage rating. Ensure compatibility with the target battery chemistry, specifically lithium-ion or lithium-polymer types. Confirm that the application requires an off-line secondary side controller architecture. Check for availability through authorized distributors as supply status may vary.

Selection Notes

Select this component when designing chargers for 2S Li-ion or Li-Po packs with an 8.4V maximum voltage. It is suitable for applications requiring integrated over-current and over-voltage protection. Consider the off-line secondary side topology requirements. This part is appropriate where programmable current limiting combined with voltage limits is necessary for efficient charging management.

Part Context

The ADP3810 belongs to a family of battery charger controllers from Analog Devices. Variants such as the ADP3810AR-16.8 support higher voltages up to 16.8V for 4-series cells. The ADP3810 and ADP3811 models generally combine programmable current limits with battery voltage limits. This specific variant targets lower voltage battery configurations.
