Product Overview: LT3650EDD-8.2#PBF

The LT3650EDD-8.2#PBF is a high-performance battery charger IC manufactured by Analog Devices Inc., designed to efficiently charge single-cell lithium-ion or lithium-polymer batteries. This compact and versatile power management solution comes in a small, low-profile (3mm x 3mm) DFN package, making it an ideal choice for space-constrained applications such as portable devices, medical equipment, and backup power systems.

Key Features

• Accurate Charge Voltage: The LT3650EDD-8.2#PBF provides a precise final float voltage accuracy of ±0.5% at 25°C and ±1% over the full temperature range, ensuring the battery is charged correctly to maximize its lifespan and performance.
• Programmable Charge Rate: The charge current is programmable up to 2A, which allows for flexibility in the design and optimization of the charging profile for specific battery requirements.
• Charge Termination: The device includes an automatic charge termination feature based on the C/10 rule, which helps to prevent overcharging and maintain battery health.
• Thermal Regulation: To protect against overheating, the LT3650EDD-8.2#PBF incorporates thermal regulation that reduces the charge current if the internal temperature of the IC exceeds a preset threshold.

Protection Features

• Reverse Battery Protection: The IC prevents damage to the charger if the battery is accidentally connected in reverse.
• Overvoltage Protection: The device includes an overvoltage protection circuit that safeguards the battery from being charged above its specified voltage.
• Input Supply Overvoltage Lockout (OVLO): This feature ensures that the charger does not operate if the input supply voltage exceeds a certain limit, preventing potential damage to the system.

Applications

• Portable Consumer Electronics
• Medical and Healthcare Devices
• Industrial and Instrumentation Equipment
• Backup Power Systems

The LT3650EDD-8.2#PBF from Analog Devices Inc. offers an optimal balance between performance, protection, and design flexibility, making it a top choice for engineers and designers looking to implement a reliable and efficient battery charging solution in their products.
