The program memory of SS80X/SS880X chips such as SS809, SS809Q, and SS880A is OTP Flash, which supports up to 12KB. OTP stands for One Time Programmable, which means that you can only program once. However, there are many uncertainties in product development, when necessary, mass production or trial production products have the appeal of replacing the program, although the above chip is only programmable once OTP Flash, in the case of meeting certain conditions, can support multiple programming, as follows.

SS882X Boost supports the maximum load capacity of 1A, and in emergency charging scenarios, SS882X Boost supports limiting current by hardware in order to support devices with large charge current such as mobile phones. In actual application scenarios, if SS882X Boost current limit does not match the undervoltage protection function of a mobile phone or other device, compatibility issues such as the inability to charge the mobile phone may occur. The specific instructions are as follows.
