Frequently Asked Questions
How low is the quiescent current of the LTC4070, and why does this matter for energy-harvesting sensor nodes?
The LTC4070 operates with a quiescent current as low as 1 µA, which is critical for always-on IoT sensor nodes that harvest energy from solar cells or RF fields supplying only microwatts. At such low self-consumption, the charger does not drain the single-cell Li-Ion battery faster than the harvested source replenishes it, enabling perpetual operation.
Can the LTC4070 float voltage be tuned to match different lithium cell chemistries?
Yes, the LTC4070 provides an adjustable float voltage threshold set by an external resistor divider, allowing the designer to precisely program the end-of-charge voltage for different Li-Ion or LiPo cells. Typical Li-Ion cells terminate at 4.2 V, while LiFePO4 cells require approximately 3.6 V — both can be configured within the LTC4070's operating range without changing the IC.
For a compact wearable PCB, how does the 8-pin MSOP footprint of the LTC4070 compare to larger charger ICs?
The 8-pin MSOP package of the LTC4070 occupies approximately 5 mm x 3 mm of board space, significantly smaller than an 8-pin DIP or standard SOIC-8 outline. For wearable devices or compact IoT tags where battery charger area must stay below 20 mm², the MSOP footprint combined with the shunt topology's minimal external component count helps achieve high integration density.
