LT3650EDD-8.2#TRPBF

Battery Chargers Overview

The LT3650EDD-8.2#TRPBF is a high-voltage, 2A monolithic lithium-ion battery charger manufactured by Analog Devices Inc. It operates over a wide input voltage range of 9V to 32V and provides a fixed output voltage of 8.2V, designed for charging two-cell lithium-ion or lithium-polymer battery packs. The device integrates a power path manager that automatically sources system power from the adapter when available and from the battery when the adapter is absent. It features a thermal regulation loop that reduces charge current to limit die temperature rise, ensuring safe operation under various thermal conditions.

Battery Chargers Feature Summary

• Integrates a power path manager for seamless system power sourcing between adapter and battery
• Includes a thermal regulation loop to reduce charge current based on die temperature
• Supports automatic recharge functionality triggered by battery voltage drop below a set threshold

Battery Chargers Applications

• Portable medical equipment requiring reliable battery charging
• Industrial handheld devices operating in variable thermal environments
• Consumer electronics utilizing two-cell lithium-ion battery configurations

Battery Chargers Procurement Notes

Verify the suffix #TRPBF indicates tape and reel packaging when ordering. Confirm the -8.2 designation matches the required 8.2V output for two-cell applications. Ensure the DFN package type aligns with PCB layout requirements. Cross-reference the specific lot traceability if mandated by quality standards. Validate compatibility with the intended input voltage range before finalizing procurement.

Battery Chargers Selection Notes

Select this component for designs requiring a compact solution for two-cell lithium batteries with inputs up to 32V. It is suitable where thermal management is critical due to its integrated regulation feature. Consider the DFN package size constraints during PCB design. This part is appropriate for systems needing automatic power path switching without external MOSFETs. Evaluate the fixed 8.2V output against the specific battery chemistry requirements.

Battery Chargers Part Context

The LT3650 belongs to Analog Devices' family of high-voltage linear battery chargers. It is distinct from switching regulators like the LT3680 due to its linear topology. The -8.2 variant specifically targets two-cell series configurations, differing from single-cell versions like the LT3650EMSE-4.2. It shares the core architecture with other LT3650 variants but differs in output voltage setting and package options.

Battery Chargers Replacement Considerations

LT3650IMSE-8.4#PBF offers similar functionality with an 8.4V output and MSOP package. LT3650EMSE-4.2#TRPBF is a single-cell alternative with 4.2V output. Verify pinout compatibility and thermal performance when substituting. Check if the target application requires the specific 8.2V setting or if a different cell count is acceptable.
