您好! 除了UCD9222、我还将在我的新设计中使用 UCD9090A。 我看到该器件上的 PMB_ALERT 输出被声明为开漏。 我看不到 UCD9222数据表中的任何地方显示其 PMBus_ALERT 输出为漏极开路、但我看到需要10K 上拉至3.3V、这让我相信它可能是漏极开路。 我想将这两个信号绑定在一起、以便 ...
在PMBus_ALERT 低电平中、对通信结果有一些过孔。 例如、PEC 位表示 UCD 接收的数据包未通过 PEC (packect 错误检查)。 此致 Yihe 向上0True向下 admin6 年多前 TI__Guru***1956055points 请注意,本文内容源自机器翻译,可能存在语法或其它翻译错误,仅供参考。如需获取准确内容...
PMBus address will be unaware that it lost arbitration, and the next command to the device with the higher PMBus address will be ignored. If the host sends a third Alert Response Address command and this device wins the arbitration, then the host will receive the higher ad...
The reason why we need to confirm this spec is we have 6pcs TPS546C23 on our board, and need PMBUS control. We need to calculate the pull high resistors value. Currently, we designonepull high resister 4.7K-ohm to 3.3V level for SMBUS_Alert. A...

We use UCD90120 but PMBUS_ALERT will always be pulled LOW, we will use the clear fault button INT will be pulled high, but will be pulled LOW immediately, our system power has no other exceptions,How to clear other faults clearly by clear fault button , why the...
