Hello, we are long time users of ICE3PCS01G. When we selected this ic the maximum operating frequency was 250Khz, now the datasheet report only 100Khz. Can you please explain this change?  We did not receive any advice about this change. We have a lot of board designed to work at 125Khz.

Thank you

Max

Hi,

Sorry for the inconvenience.

Value in the datasheets is regularly cross-verified with test data.

In the datasheet, you can see the frequency setting resistor is also verified. The new data is more reliable than the previous.

Regards,

Thank you for your answer. My concern is if a little higher working frequency can cause problems (eg. R freq.=39KOhm instead of 43KOhm)

Regards
