TPS2592ZA / Auto-Retry

Other Parts Discussed in Thread: TPS2592ZA

Hi Team,

I would like to ask two questions about TPS2592ZA(Auto-Retry).

1)
The datasheet shows the following.
----------------------------------------------------
(page.14)
The TPS2592xA device will remain off during a cooling period until device temperature falls below TSHDN –
10°C, after which it will attempt to restart. This ON and OFF cycle will continue until fault is cleared.
----------------------------------------------------
What does the "fault" above indicate?
Does it indicate the state of over current (current limit is exceeded)?

2)
It seems Figure22 shows the timing of Auto-Retry.
When does the device temperature falls below T_SHDN - 10℃?
I can't also figure out what is the trigger of ① and ② respectively.




Your support would be appreciated.

Best Regards,
Yaita / Japan disty
