Frequently Asked Questions
What charge voltage and maximum charge current does the LTC4002ES8-4.2#PBF deliver?
The LTC4002ES8-4.2#PBF charges single-cell Li-Ion batteries to a fixed 4.2V termination voltage. The programmable charge current can be set up to 1A using a single external resistor, and the quiescent supply current is only 0.095mA, minimizing standby drain in battery-powered systems.
How does the LTC4002ES8-4.2#PBF protect the battery and circuit during charging?
The IC includes internal thermal regulation that automatically reduces charge current when the junction temperature exceeds safe limits, preventing thermal runaway. It also provides automatic recharge to top off the cell once voltage drops below a threshold, and the 8-pin SOIC package dissipates heat efficiently at charge currents up to 1A.
Can the LTC4002ES8-4.2#PBF charge from a USB 5V input without extra regulation?
Yes, the LTC4002ES8-4.2#PBF accepts input voltages from approximately 4.5V to 10V, making it directly compatible with 5V USB power sources. Its linear charger topology requires no external inductors, reducing BOM size and simplifying EMI management in compact 8-pin SOIC board designs.
When would you choose LTC4002ES8-4.2#PBF over a switching Li-Ion charger?
The LTC4002ES8-4.2#PBF suits applications needing a low-noise, inductor-free design with a minimal footprint, such as medical or audio wearables where switching regulators introduce unacceptable EMI. For charge currents below 500mA and input voltages near 5V, the linear architecture provides adequate efficiency while keeping board area under 50mm².
