Part Number: TPS65982

Dear Team,

Could you provide the information about the transition time from sleep mode to normal operation mode?

My customer would like to wake up PD over I2C, so they send multiple commend to PD.

From the test, PD takes 1.51ms to wake up and response the second I2C commend.

Could we reduce this transition time?

Thank you.

Hi Jim,

This transition time cannot be changed on our device.

Thank you,
Eric

Hi Eric,

Could you provide the related spec? I cannot find it on current data sheet.
What is the recovery time for PD waking up?

Thank you.

Jim:
Internally we have measured a similar number. But, when discussing with the firmware team they recommend 10 msec from sleep to wake to cover all corner cases.
