Hi TI

Can you provide a fault table of TPS12111LQDGXRQ1 for me? I want to know when fault occurred，the status of every PIN，and how to recovery.

Hi Ling,

Thanks for reaching out.

TPS1211-Q1 is simple device. It has two fault outputs FLT_T/ and FLT_I/

FLT_T/ pin asserts low when overtemperature fault is detected

FLT_I/ pin asserts low after the voltage on the TMR pin has reached the fault threshold of 1.1V. this pin indicates the pass transistor is about to turn off due to an overcurrent condition. The FLT_I pin does not go to a high-impedance state until the overcurrent condition and the auto-retry time expire.

BR,

Rakesh

Thanks for your reply.

How IMON voltage variable，when over temperature & overcurrent? Did IMON turn high when fault occured? Such as HSD like TPS2HB16AQPWPRQ1?

IMON is an analog voltage output proportional to the load current. When fault occurs, the MOS is turned off and load current becomes zero so IMON = 0V
