Hi all

im trying to understand what is the output signal on SMU.FSP0 (P33.8).
it is connected to ERR pin on PMIC.

it seems like the PMIC is expecting some toggling signal (like pwm 50%DC).

how can i get access to related official application notes documents? (i have access to MyICP, but how can i request specific docs?)

 

thnaks.

Hello, Assaf.

The TLF_35584 has two time parameters:ΔtDET_LF and ΔtDET_HF.

>>As for immediate reaction mode

If the continuous time of low voltage level or high voltage level is out of range (ΔtDET_HF ,  ΔtDET_LF), the safe state pin will action shown in below figure.Note:It can cover the scenario of PWMduty=50%.
