Frequently Asked Questions

What charge current can the LTC4058EDD-4.2#PBF deliver and how is it set?

The LTC4058EDD-4.2#PBF supports programmable charge current up to 600 mA, set by a single external resistor connected to the PROG pin. This allows designers to tailor charging speed to battery capacity, making it practical for single-cell Li-Ion packs ranging from 100 mAh to over 1000 mAh in portable products.

How does the LTC4058EDD-4.2#PBF protect against overheating during fast charging?

The IC incorporates automatic thermal regulation that reduces the charge current when the junction temperature approaches 125°C, preventing thermal damage without any external components. This feature is especially valuable in compact PCB layouts where heat dissipation is limited, allowing the charger to operate near its 600 mA maximum safely.

What float voltage does the LTC4058EDD-4.2#PBF use, and which battery chemistry is it compatible with?

The LTC4058EDD-4.2#PBF has a fixed 4.2 V float voltage optimized for single-cell Lithium-Ion batteries. The ±1% accuracy of the 4.2 V regulation ensures full capacity utilization while protecting cells from overvoltage, making it compatible with standard Li-Ion chemistry used in consumer and industrial portable applications.

When is the LTC4058EDD-4.2#PBF a better choice than a switching charger IC for a portable design?

The LTC4058EDD-4.2#PBF suits designs where simplicity and low EMI matter more than efficiency, particularly when the input voltage is close to 4.2 V and power dissipation in the 8-DFN package is manageable. Its linear architecture eliminates switching noise, making it preferable in audio accessories, medical wearables, and RF-sensitive devices where switching regulators would introduce interference.
