Part Number: USB-PD-CHG-EVM-01
Other Parts Discussed in Thread: BQ25792

If 4.3V is applied, is there a risk of damaging the chips since the TPS25750D and BQ25792 specify a maximum I2C line voltage of 4V?

Hi Swengwoo,

I would not expect damage on the BQ25792 with is 6V abs max rating on SDL/SCA. However, the TPS25750D I2C lines have a max rating of 4V so immediate damage or compromised long term reliability is possible.

Regards,

Jeff
