Hi,
We can find the following sentence on the datasheet P.57. I seem when two retries are failed, TPS65219 stops the power-up.
For every detected Shut-Down fault, irrespective if prior to the sequence due to unsuccessful discharge, during the power-up-sequence or in ACTIVE or STBY state, the retry counter (RETRY_COUNT in POWER_UP_STATUS_REG register) is incremented. The device attempts two retries to power-up. If both fail, a power-cycle on VSYS is required to reset the retry counter.
Also, P.130, Description of RETRY_COUNT is as follows: On this sentence, when three retries are failed, TPS65219 stops the power-up.
Reads the current retry count in the state machine. If RETRY_COUNT = 3 and is not masked, device does not power up.
How many times does TPS65219 retry power-up? Two times or three times?
Although I think answer is three times, I want to confirm it. Please advise us.
Thanks and best regards,
M.HATTORI.
