现在做AM3358BZCZA100项目,现在TPS65910A3启动5S后,会自己关断,BOOT1,BOOT0设为10模式;PWRON直接对地。请问是配置问题吗

可能是PWRON直接接地导致的问题,PWRON一般是外接PUSH BUTTON.
When the PMIC is in ACTIVE mode, if the button is pressed for longer time than tdPWRONLP, the PMIC generates the PWON_LP_IT interrupt. If the processor does not acknowledge the long press interrupt within a period of tdPWRONLPTO – tdPWRONLP, the PMIC goes to OFF mode and shuts down the DCDCs and LDOs.
