CYPD3175 是需要烧写固件,如果您烧写的是CYPD3175 direct feedback的固件没有任何的改动,Cypress SDK的固件是在以下情况开启VBUS IN /DIS PIN脚放电。当然接下的情况都是基于VBUS_IN_DISCHARGE_EN (@file stack_params.h /* VBUS in discharge enable */ #define VBUS_IN_DISCHARGE_EN (1u) )使能...
VBUS是USB模块的输入信号,用于在自供电(VDD供电)模式下判断USB总线是否连接上。这个引脚是一个高阻输入脚,不消耗多少电流。总线供电模式下芯片在运行时VBUS必然是连接状态,一般无需再判断VBUS的状态。 VREG IN脚是输入给USB MCU内部的降压模块(Voltage Regulator)的输入引脚。在降压模块使能的时候这个引脚是系统电流的...

Architecture for VBUS pulsing in an Ultra Deep Sub Micron (UDSM) process for ensuring USB-OTG (On The Go) session request protocol, the architecture being of the type wherein at least a charging circuit is deployed, uses a diode-means connected in a forward path of the charging circuit. ...
Part Number: TPD4E05U06 Other Parts Discussed in Thread: TPD6S300A Hello, Based on the below E2E forum discussions on protection from VBUS: our understanding
Is it both need input power of USB_H1_VBUS and USB_OTG_VBUS? (i.e. If either is inputted, is power supplied to both of Host1 Phy and OTG Phy?) [Q2] If good in either input USB_H1_VBUS or USB_OTG_VBUS, Why does two VBUS ports exist? Best Regards, Keita...
The CXAS42201 is a high-speed, low-power double-pole/ double-throw (DPDT) analog switch that operates from a single 1.8V to 5.5V power supply and it can be powered directly from VBUS of USB interface. CXAS42201 is designed for the switching of high-speed USB 2.0 signals in handset and...
