Dear support team

Is the GDRV pin surely set to L level when TPS40210-Q1 is disabled?

My concern is whether there is no floating state.

Hi Tomohiro,

When the TPS40210 is disabled the GDRV pin is pulled low by an internal resistor.

Thanks,

Garrett

Hello Garrett-san

Thank you for quick support.

What is the value of the internal resistance?

Rough value is helpful for us.

Hello Nagasawa-san,

The internal resistance is about 250kOHm.

Thanks,
