SC89619
High Efficiency, Synchronous 1.26A Buck Charger for 1 cell Li-ion Battery
with NVDC Power Path Management and 20mA Termination
The SC89619(D) is a 1.5MHz highly integrated switch-mode buck charger for 1 cell Li-ion 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 1.26A 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.
