Intel_英业达KITTY14I UMA_HP_DV4-4000(HM65)保护隔离和待机分析
学习有效期 1000天 （随到随学）
简介
本课程以PPT的形式讲解了Intel_英业达KITTY14I UMA_HP_DV4-4000(HM65)保护隔离和待机分析，适配器到公共点需要经过Q302和Q303两个隔离管，分别受控与ADP_EN2（高电平）和ACDRV（高电平），ADP_EN2来自与EC，实测发现EC只需要得到供电就自动发出ADP_EN2。
根据引脚定义：当ACDET大于0.6V后，ACDRV会自举升压保持比CMSRC高6V，ACDET来源与+VADP分压，+VADP只要高于4.3V即可使ACDET大于0.6V，芯片发出高电平的ACDRV（CMSRC+6V）。
具体的讲解请看本课程内容。
