FP6806-Integrated Charger/Booster Converter


FP6806-Integrated Charger/Booster Converter with Power Path Control DataSheet

General Description
The FP6806 is a highly integrated Power Management IC with switch-mode Li-Ion Battery
Charger and DC-DC Boost Regulator for power bank use. It detects battery voltage and charges the
battery in three phase: trickle-current, constant-current and constant-voltage. When in the
constant-voltage mode, it is set to auto-termination as the charge current drops below termination
current. A charge cycle restarts when the battery voltage falls below the restart threshold. Its low
impedance power path optimizes the operation efficiency, reduces charging time and extends the
battery lifetime during the discharge phase. The device provides various safety features in the charge
and discharge phase, including over-current protection and over-voltage protection. When the junction
temperature exceeds 120
, the thermal regulation will reduce the charge current to almost zero. The
FP6806 is available in the SOP8-EP package to reduce PCB space.
