Overview
The ADP3810AR-8.4-REEL is a secondary side, off-line battery charger controller manufactured by Analog Devices Inc. It is designed for lithium-ion and lithium-polymer battery chemistries. The device operates within an ambient temperature range of -40°C to 85°C. It utilizes an 8-SOIC package with a width of 3.90mm. The maximum supply voltage is 16V. This component functions as a constant current, constant voltage charger by combining programmable current limits with battery voltage limits.
Feature Summary
- Combines programmable current limit with battery voltage limit
- Provides constant current and constant voltage charging profiles
- Designed for secondary side, off-line applications
Applications
- Lithium-ion battery charging systems
- Lithium-polymer battery charging systems
- Off-line battery charger controllers
Procurement Notes
Verify RoHS compliance status prior to procurement, as this specific variant is listed as non-compliant in available documentation. Confirm the 8-SOIC package dimensions and operating temperature range requirements match the target design specifications. Ensure the 16V maximum supply voltage rating is sufficient for the intended circuit environment. Cross-reference the REEL packaging designation with manufacturing lot details to ensure authenticity and traceability from Analog Devices Inc.
Selection Notes
Select this component when designing chargers for single-cell lithium-ion or lithium-polymer batteries requiring off-line control. The fixed voltage limit configuration suits applications where the battery pack voltage does not exceed the device's rated maximums. Consider the surface-mount 8-SOIC package for space-constrained PCB layouts. Evaluate the -40°C to 85°C operating range against environmental conditions. This controller integrates essential charging parameters, reducing external component count compared to discrete solutions.
Part Context
This part belongs to the ADP3810 series, which includes variants like the ADP3811. The series combines current and voltage limiting for efficient battery management. The ADP3810AR-8.4-REEL specifically targets lower voltage packs compared to higher voltage counterparts like the ADP3810AR-16.8. It serves as a dedicated controller rather than a complete power stage, requiring external switching components for implementation.
Replacement Considerations
Check for direct pin-compatible substitutes within the ADP3810 family, such as the ADP3811, if functional differences are acceptable. Verify that alternative controllers support the same lithium-ion/polymer chemistry and voltage limits. Ensure replacement parts meet the required 8-SOIC package and temperature specifications.
