Using the MIC8030/MIC8031 allows for a derating of 50%/70% if operated at 35V; the HI-8010 allows for no derating at 35V and the S4520 allows for no derating at 32V.

However, the high voltage supply must be positive with respect to ground for the MIC8030/MIC8031. Both AMI and HOLT use a negative High Voltage. See MIC8010/11/12/13 family for drop in replacements in existing sockets. 6 MlC8030/MIC8031 Application Hints on Compatibility with Display Drivers Produced by AMI and HOLT Seg 27 7 39 Seg 17 When placing the MIC8030/MIC8031 in a pin compatible configuration on a board which previously used a HOLT or AMI device, care must be taken before changing the polarity of the High Voltage Supply, to reverse the direction of any polarized filter capacitor on the High Voltage line, as well check any other circuit (like a zener diode, etc) which contacts the High Voltage line.
