Other Parts Discussed in Thread: UCC27200
This is an add question from a previous request concerning the UCC3895 drive specification. I trying to understand the DRIVE capabilities of the OUT-A,B,C,D. I am reviewing the data sheet SLUS157Q.
1) On page 2, I see 100 ma Complementary Outputs for OUT-A,B,C,D.
2) On page 5, OUT-A,B,C,D, the data shows VCC + 0.3. I think it should this say VDD + 0.3?
3) On page 8, "OUTPUT", it states "Voh (All Outputs) = 250mV @ 10 ma".
These three items seem a contradictory. How can an OUTPUT HIGH be 250mV @ 10ma, that seems too low.
Item 1) and item 3) don't match. The 250mV @ 10ma could not drive a COIL.
Please help me understand the real driving specifications for these four outputs OUT-A,B,C,D.

I'm also referencing SLUU109B for my UCC3895 design. This doc shows on page 5, (Schematics), here the UCC3895 is directly driving the UCC27200.
Looking at the Data sheet for UCC27200 - page 5, this part requires an INPUT of "V-HIT = 5.8V".
Please help me understand how the UCC3895 is driving the UCC27200, from these data sheets.
Thanks for your help in this matter.
