TPS2490: OUT pin damage

Ella KIM

Part Number: TPS2490

Hello Team,

I'm wondering if OUT pin can be damaged if a voltage is applied while input node is open. For customer application, 28V would be applied to OUT while VCC is open.

Hi Ella,

There will be possibility of stressing the GATE with OUT pin powered by active source. They can use back-to-back FET configuration in common source topology to avoid such case. Can you share customer schematic to review.

Best Regards,

Rakesh
