Junction Temperature
Enough current should be supplied into the VCC pin to keep the internal 15.6V zener clamp diode on
this pin regulating its voltage.
Due to the fact that the RT input is a voltage-controlled current source, the total RT pin current is sum
of all of the parallel current sources connected to that pin. For optimum oscillator current mirror
performance, this total current should be kept between 50μA and 500μA. During the preheat mode,
the total current flowing out of the RT pin consists of the RPH pin current plus the current due to the
RT resistor. During the run mode, the total RT pin current consists of the RUN pin current plus the
the current due to the RT resistor.
