TPD3S714-Q1: Inquire about TPD3S714-Q1

Hi Roy,

1. No, it cannot work if you floated VBUS due to this pin is to supply for  internal circuit.

2. Yes, you can directly connect EN to high and float FL.

BTW, what is your application? If you just need D+/D- switch, maybe you can select other products.

Ansel

Hi Ansel,

Thank you for your quick reply.

The problem we encounter is that customer uses some twisted type C cables to plug into infotainment, and it is possible that DP/DN is shorted to GND and then infotainment DP/DN is damaged.

For USB role of infotainment, it supplies 5V for USB devices. Do you help us check whether this following connection can work properly?

In short, we only need D+/D- protection IC.

Roy

Hi Roy,

NO, it is no possible to work if there is no 5V VBUS. And I know there are some discrete solution can meet your requirement. Our product line should have this device.

HI Ansel,

We have 3.3V or 5V rail could provide to protection IC, but we dont need OV function on VBUS like TPD3S714-Q1.

Could you let me know who may help me find the IC?

Roy

Hi Roy,

You can choose TPD3S713-Q1, and supply 5V on VBUS, but I think it is noncompetitive due to there is too function wasting.

Hi Ansel,

I see.....

Do we have simple part only have Short-to-VBATT Protection function?

Hi Ansel,

I would like to double check the function. As below table, it looks like that VD+/VD- transmission is not related to VBUS_CON or VBUS_SYS. 

If we give power on VIN pin and then VD+/VD- MOSFET could operate normally. Could you help check it.
