The SC9802 is a highly integrated SoC for power bank, with an integrated two-channel charger to support power management and synchronous boost conversion.Two chargers can work at the same time, supporting 5V3A and 12V2A dual charge-discharge. The 5V charger of SC9802 integrates Type-C protocol and smart USB protocol (compatible with DCP recognition function, compatible with BC1.2, Apple and Samsung mobile phones), can support Type-C interface adapter charging, Type-C interface discharge and USB-A interface discharge, providing 5V4A charge and discharge function. High voltage charger supports fast charging protocol for power bank. Work with an external protocol IC can provide up to 12V2A 24W discharge capacity. The two-channel charger structure of SC9802 ensures the true and fast charging function when working in two-channel mode, which can effectively reduce the difficulty of the overall solution, provide a complete solution for the power bank and reduce the BOM cost. SC9802 supports charging management functions such as trickle charge, constant current charge, constant voltage charge, charge cutoff and recharge. The built-in 10bit ADC ensures the real-time monitoring of the battery voltage and current and the voltage and current of each port, accurately displays the battery power, and supports multiple over-voltage protection and over-current protection to improve the reliability. When no load, it automatically enters the sleep mode, reduces the static current, and ensures that the battery consumption current is below 100μA. SC9802 supports battery power display and button function.The SC9802 is in a 44-pin 5x6 QFN package.
