TPS25750: AttachedAsSink of GPIO Events

K.Yaita

Part Number: TPS25750

Hi Team,

I would like to ask about AttachedAsSink of GPIO Events.
Could you tell me the delay time (max) from ”VBUS is applied" to "GPIO goes high"?

I would also like to know the delay time (max) from "VBUS is applied" to "sink current starts to flow".

Best Regards,

Yaita,

This timing will be somewhat variable with the patch size.

I can measure this timing tomorrow with and EVM and the current patch and update you.

Hi Chuck-san,

Thank you for your kind support.
By the way, what "patch size" means?

Best Regards,
Yaita

Yaita-san,

When the TPS25750 boots, it loads a firmware and configuration patch from the eeprom. The size of this file will vary with the binary that is provided. It can shift by several hundred bytes which will shift the boot time because of the I2C transactions required.
