CPS5211
Application
TWS Box
1 Cell Li-on Application
Wireless & VBUS Charging
The CPS5211 is a highly integrated single-chip PMIC for VBUS and wireless receiver, switching charger plus boost circuitry. CPS5211 will auto judge the input source to select VBUS or wireless charging. Its input has 15V tolerance to enhance the input voltage robust likes VBUS plug-in. The switching charger can support maximum 1A charging current to decrease the charge time. The boost can support 5V/0.5A output.
