Frequently Asked Questions
What is the maximum charge current of the LTC4065LEDC, and how is it programmed?
The LTC4065LEDC supports a maximum charge current of 250 mA, set by a single external resistor connected to the PROG pin. This resistor-programmable approach lets designers target any charge current from a few milliamps up to 250 mA to match the battery capacity and thermal budget of the application.
How does the LTC4065LEDC protect the battery and itself during sustained charging without an external temperature sensor?
The LTC4065LEDC integrates an automatic thermal regulation loop that monitors the die junction temperature and reduces the charge current when it approaches approximately 100°C, preventing overheating without an external NTC thermistor or MCU supervision. This built-in fold-back ensures safe operation in the 2×2 mm DFN package even without a heat spreader.
In which form-factor-constrained applications does the 2x2 mm DFN-6 package of the LTC4065LEDC provide a competitive advantage?
The LTC4065LEDC occupies a 2 mm × 2 mm PCB footprint in its 6-pin DFN package, making it one of the smallest complete Li-Ion charger solutions available. This size is critical in true wireless earbuds, smart rings, medical patches, and coin-sized sensor nodes where every square millimeter of board space is shared among power management, RF, and sensing components.
