High Efficiency, Synchronous 3A Buck Charger for 1 cell Li-ion or LiFePO4 Battery with NVDC Power Path Management
SC8958
High Efficiency, Synchronous 3A Buck Charger for 1 cell Li-ion or LiFePO4 Battery with NVDC Power Path Management
The SC8958 is a 1.5MHz highly integrated switch-mode buck charger for 1 cell Li-ion or LiFePO4 battery applications and NVDC system power path management, which separate the system load and charge current, also the system can power up with deep depletion battery. System can get the power from VBUS, VBAT or both. It supports 3.9-13.5V input voltage, up to 3A charging current and provide battery charge management functions including trickle charge, constant current charge, constant voltage charge, charge termination, auto recharge and charging status indication.
