Pull-up related for MPM82504

Hi there

I am writing because I have questions about the MPM82504 product when using the MTP program.

Looking at the datasheet, it says that the TAKE pin should be pulled up to 3.3V.
For the 4-channel basic design, the datasheet says to pull up the TAKE pin through each VCC pin of the built-in LDO.

However it is said that the voltage of the built-in LDO goes up to 6V when the MTP program is running.

  1. Will there be no problem if a voltage of 6V is momentarily applied to the TAKE pin and PASS?
  2. Or is it safe to apply a separate external 3.3V power source?

thank you for your support


It is ok for the take PIN to be tied to the parts VCC pin. It can withstand the brief voltage transients caused by programming up to 6V.
