Southchip provides highly integrated SoC solutions for 1S lithium battery powered power banks. The SoC can support multiple USB ports, and consume low standby current, and can intelligently detect the insertion and removal status of adapters and mobile phones, and automatically control the charge and discharge for all USB ports. They can judge the type of adapters and mobile phones through DPDM and CC signals, optimize the charge and discharge current, so to make efficient use of battery energy. They can also automatically monitor the battery voltage and display the battery gauge through LEDs. They also support various button functions, like the long time low-current discharging mode for bluetooth headset. The SoC solutions support higher integration, fewer peripheral components, so to save the BOM cost, and facilitate the rapid development and production to the market.
