(1)
All electrical characteristics having room temperature limits are tested during production at TA = 25°C. All hot and cold limits are
specified by correlating the electrical characteristics to process and temperature variations and applying statistical process control.
(2)
VCC provides self bias for the internal gate drive and control circuits. Device thermal limitations limit external loading.
