What are the limits of the TLD2132-1EP PWMI pin input frequency and input pulse conditions?

The datasheet didn't have any stipulations for each.

Hi @Mac_Komatsubara
Thanks for posting on the Infineon Developer Community.
The PWMI pin input frequency for TLD2132-1EP will be dependent on ton(PWMI) & toff(PWMI).
The maximum value of the ton(PWMI) & toff(PWMI) are 15usec and 10usec respectively.
So,the PWMI pin input frequency can be calculated as 1/( ton(PWMI) + toff(PWMI)) which is 40kHz.
The typical value of PWMI low threshold(VPWMI(L)) & PWMI high threshold VPWMI(H) are 1.7 volt & 2.7 volt respectively.
I hope the information will be useful for you.
Please feel free to contact in case of any further clarification.
Best Regards,
Kanahaiya
