UCC21520-Q1: About NC pin

Part Number: UCC21520-Q1

Hi,

Customer wants to connect pin 12 and pin 13.
(The two pins are connected but floating.)
The reason is to reduce the number of pin probe tests in the application.

Is it OK to connect pins 12 and 13?
If it is NG, please tell me the reason.



Regards,
Yusuke

    Tsukui,

    So long as NC pins are floating and creepage and clearance from ch-A to CH-B are maintained, you may short the 2 as there no internal connections according to Section 5 of datasheet.
