I2C Controlled, Maximum 13.5V Input, Charger with NVDC Power Path Management and OTG Output
PQ89620
I2C Controlled, Maximum 13.5V Input, Charger with NVDC Power Path Management and OTG Output
The PQ89620 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 3.5A 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.
