Single-cell Li-Ion charger with PowerPath control
The LTC4085EDE-3#TRPBF is a single-cell Li-Ion/Polymer battery charger from the PowerPath series, integrating a USB-compatible input and PowerPath load-sharing control so the system runs from the USB bus when available and draws from the battery when it is not. Charge current is programmable up to 1.5 A max, and the termination voltage is set to 3.95 V for the battery pack — a slightly lower float than the common 4.2 V, which can extend cycle life at the cost of a small reduction in capacity per cycle.
