you can get 4 chips each, but they make two kinds in PDIP8, so actually 10chip each.
and then theres the 27321/22 extended temp range.
so you will end up getting 20chip each.

For now I can only get 10 samples of UCC37321 and UCC37322 chips are causing me problems. I first select one kind in the PDIP8 package and get this:

1177190141 515 FT24065 Untitled1


and when I trie to add the other one in the PDIP8 package I get this:
1177190141 515 FT24065 Untitled2

Humm... weird, I got thru a few times by doing that, maybe they found out?

One of my friends got like 4 accounts, seems like you only need to give them a different email address.

If you're blowing gate driver chips, then you should take the time to determine why rather than just keep replacing them.

People like your friend who abuse the system and foul the agreement between themselves and TI will cause TI to cease sampling. Don't do it. Tell your friend not to do it. It's deceptive, misleading, and unfair.

Well I'm a beginner and I think that every one here blown more than five driver chips when they were experimenting like me. tongue And now I need more. And lets face it they blow very early.
