TUSB4020BI: 与同系列芯片TUSB4041I器件手册描述不一致

Part Number: TUSB4020BI
Other Parts Discussed in Thread: TUSB4041I,

您好,

原来设计用的TUSB4041I,现在想用TUSB4020BI,但是在阅读器件手册时发现有3个引脚描述不一致。本以为同系列的芯片应该没有这种差异,所以想确认一下手册是否有误。

TUSB4041I中如下图:

TUSB4020BI中如下图:

从中看到PWRCTL_POL的管脚类型和功能描述在两个手册中是相反的;

FULLPWRMGMTz/SMBA1和GANGED/SMBA2/HS_UP的IO类型和内部上下拉配置不一样。
