CSD95485RWJ: the minimum withstand of the CSD95485's vin-sw

hello,

The min negative voltage during 10nS is -7V. The body diode will turn on when the voltage is -0.3V.

Hi Mahmoud,

is there any risk? or need reserve margin(80%)?

In the worst case seen under short or transient conditions, should the customer leave a margin?

can you please send scope picture? The correct measurement should be done wit differential probe and very close to device pins.

Hi Mahmoud，

The scope wave picture is as below.

Is it only transient? Is there subber implemented on SW?

Hello,

It is OK during transient.

Hi Comi,

I think the -6V is due to ringing on SW. does the customer board has RC snubber? with lower ringing the VIN to SW negative voltage is lower.
