TPS2663: About MODE pin

Hi,

I have a question about the protection function of TPS26631.

1. Is it correct to understand that the latch-off/auto-retry of the following protection functions can be switched with the MODE pin?

・OVP

・Active Current Limiting With 2 × IOL Pulse Current Support

・Short-Circuit Protection

・Start-Up With Short Circuit on Output

・Thermal Shutdown

2. If it is set to auto-retry, could you tell me the ton for each protection function?

Best Regards,

Nishie

Hello Nishie,

Welcome to E2E.

1. Yes, Mode pin can be set to different function.

2. Ton time is faster in case of auto-retry turn on. It doesn't follow the dvdt start-up during that. However, I am not sure of the Ton time. I will check and let you know

Thanks

Amrit
