Renesas provides various documentation for their OVP products including a whitepaper discussing the causes of over-voltage faults and their remedy through integrated OVP transceivers. Additionally, a datasheet listing the parametric differences between the individual devices of the entire ISL3245xE OVP transceiver family is available. Finally, they provide IBIS models, consisting of tables with current, voltage, and timing information. IBIS models simulate much faster than SPICE models, with only a slight decrease in accuracy. Non-convergence issues, often encountered with SPICE, are eliminated in IBIS simulation. Renesas provides IBIS models for all of its transceiver products. They are easy to use and are freely available from their web site.
