Frequently Asked Questions
How is the charge current of the LTC4059EDC#TRPBF set in a circuit, and what range is supported?
The charge current of the LTC4059EDC#TRPBF is programmed using a single resistor connected to the PROG pin, with the relationship ICHG = 1000/RPROG amperes. This allows charge currents from approximately 100 mA to 600 mA to be set, for example a 1.67 kΩ resistor sets 600 mA, while a 10 kΩ resistor sets 100 mA, giving designers flexibility to match the charge rate to battery capacity.
What happens when the LTC4059EDC#TRPBF thermal regulation engages during charging from a 5 V USB source?
When the die temperature exceeds approximately 110°C due to power dissipation at high charge currents, the LTC4059EDC#TRPBF automatically reduces ICHG to limit self-heating. For a 5 V input charging at 600 mA into a 3.7 V battery, dissipation reaches about 780 mW — thermal regulation prevents thermal runaway on compact PCBs without requiring a dedicated NTC thermistor or external thermal protection circuit.
In which portable device segments does the LTC4059EDC#TRPBF compete with discrete charger solutions?
The LTC4059EDC#TRPBF directly replaces discrete linear charger circuits built from op amps, MOSFETs, and sense resistors in wearables, Bluetooth earbuds, and coin-cell backup charging circuits. Its 6-pin DFN measuring 2 mm × 2 mm is up to 80% smaller than an equivalent discrete solution, and the integrated 4.2 V reference eliminates the external precision resistor divider required by general-purpose LDO-based charger designs.
