T his condition will shorten the off time at frequencies 30kHz, and is magnified at high temperatures. T his condition does not occur with a Darlington configuration, since the output switch cannot saturate. If a non-Darlington configuration is used, the following output dri ve condition is recommended. http://www.SeCoSGmbH.com/ Any changing of specification will not be informed individual 01-Jun-2002 Rev.
