Applications
The LTC4067EDE#PBF USB power manager is designed for portable devices such as handheld instruments, wearables, and IoT nodes that charge a single-cell Li-Ion or LiPo battery from a 5V USB port or 6V wall adapter input while simultaneously powering the system load. Its power path architecture allows the system to run from USB input power at up to 1A while the battery charges independently, eliminating the need for external Schottky diodes. The 12-pin DFN package and integrated protection features simplify the charger design in space-constrained mobile products.

Frequently Asked Questions
How does the LTC4067EDE#PBF manage system power when USB is connected and the battery is low?
The LTC4067EDE#PBF uses an automatic power path control architecture that draws up to 1000mA from the 5V USB input to simultaneously power the system load and charge the Li-Ion battery. When USB current demand exceeds the programmed limit, the IC dynamically reduces charge current to maintain the 5V input regulation point, ensuring the system remains powered even with a deeply discharged or absent battery cell.
Can the LTC4067EDE#PBF charge Li-Polymer batteries, and what cell voltage does it target?
Yes, the LTC4067EDE#PBF supports both Li-Ion and Li-Polymer single-cell batteries, charging to a final float voltage of 4.2V per cell with plus or minus 0.5% accuracy. The programmable charge current up to 1000mA via an external resistor allows designers to match the 1C charge rate of cells from 100mAh to 1000mAh capacity. The NTC thermistor input suspends charging outside the safe 0°C to 45°C temperature window.
What PCB area does the 12-pin DFN package of LTC4067EDE#PBF occupy compared to SOIC alternatives?
The 12-pin DFN package measures 3mm × 4mm with 0.65mm lead pitch and a 2.5mm × 3.5mm exposed thermal pad underneath. Total footprint is approximately 12mm², which is significantly smaller than SOIC-8 alternatives at around 29mm². The exposed pad requires reflow soldering for reliable thermal contact, so a hot-air station at 250°C is recommended for rework with appropriate stencil apertures.
When would a designer choose LTC4067EDE#PBF over a simpler charger IC without power path management?
A designer selects the LTC4067EDE#PBF when the system must run immediately on USB power regardless of battery state, since power path management delivers output from 4.35V to 5V to the load even with a zero-volt battery. This is essential for medical devices, GPS trackers, and industrial handhelds where dead-battery startup is a hard requirement, and eliminates the external Schottky diode and OR-ing circuit typically needed in simpler 2-component charger designs.
