1. 20 Volts is the maximum operating voltage because above this level the FAILSAFE feature shuts down the output stage.
2. Thermal slopes are shown in fig. 2
3. This value is present when the voltage sensed at the " S" or "VGO" terminal is between VUV and VOV. When the voltage sensed
= -35°C to 150°C unless otherwise specified)
at the "S" or "VGO" terminal is above VOV the Minimum Field Duty-Cycle will be 0 %.
