• UC1842A: UC1842A timing resistor

  

  Andrew Massey

  Part Number: UC1842A Hi, The UC1842A datasheet and applications literature is stating that the timing resistor should be no lower than 5k. However, that means our minimum dead time is too short. Can we use 2k7 instead? We want to use 2k7/6n8 for the…

  Part Number: UC1842A-SP The UC1842A-SP says that it is tolerant to 30krad TID, but does not show reports for SEE data. My understanding is that it's a bipolar part, and so some SEUs will occur, but likely no destructive SEEs. Am i missing a radiation…
