What is LT3650EDD-8.4#PBF used for?

The LT3650EDD-8.4#PBF provides a complete 2-series-cell Li-Ion charging front-end for portable industrial instruments, handheld medical devices, and ruggedized field equipment. Its 2 A charge rate and 8.4 V float voltage enable fast, safe charging of dual-cell 7.4 V nominal battery packs from standard AC adapters or high-voltage solar inputs. The single-IC linear charger architecture reduces BOM complexity and EMI compared to switch-mode alternatives, making it attractive for noise-sensitive medical and precision measurement equipment.

Frequently Asked Questions

What is the float voltage and maximum charge current of the LT3650EDD-8.4#PBF, and which battery configuration does this target?

The LT3650EDD-8.4#PBF is factory-programmed to a fixed 8.4 V float voltage and delivers up to 2 A of charge current, which precisely matches the fully charged voltage of a 2-series-cell lithium-ion battery pack with a 7.4 V nominal voltage. This makes it a drop-in single-chip charger for dual-cell packs used in handheld instruments and portable medical devices.

Why would a designer choose the linear architecture of the LT3650EDD-8.4#PBF over a switching charger for medical equipment?

The LT3650EDD-8.4#PBF uses a linear (non-switching) charge topology, which generates no high-frequency switching noise that could interfere with sensitive analog measurement circuits or radio receivers in medical instruments. The tradeoff is higher power dissipation compared to a switch-mode design at 2 A charge current, but this is acceptable in medical equipment where EMI compliance margins are critical and thermal dissipation can be managed with the DFN exposed pad.

How does the adjustable charge threshold feature of the LT3650EDD-8.4#PBF benefit custom battery pack designs?

The LT3650EDD-8.4#PBF includes an adjustable threshold pin that allows designers to tune the charge termination or input current limit using external resistors, without requiring a microcontroller or fuel gauge IC. This programmability accommodates battery packs with slightly different capacity or chemistry specifications than the nominal 2-cell Li-Ion configuration, reducing the need for firmware changes when qualifying alternative battery suppliers.

What is the package type of the LT3650EDD-8.4#PBF and how does the exposed pad affect thermal design?

The LT3650EDD-8.4#PBF uses a 12-lead DFN (Dual Flat No-lead) package with an exposed thermal pad on the bottom, which must be soldered to a PCB copper pour to dissipate heat during 2 A charging. Since the linear charger drops voltage across the internal pass element, proper thermal design of the copper pour and any heatsinking vias is required to keep the junction temperature below the maximum rated limit when charging from a high input voltage such as 12 V.
