Recommended Operating Conditions

For proper operation the device should be used within the recommended conditions. All voltage parameters are absolute

voltages referenced to COM, all currents are defined positive into any lead

Note 2:

Sufficient current should be supplied to the VCC pin to keep the internal 15.6V zener clamp diode on this pin

regulating its voltage.

Note 3:

Due to the fact that the RT pin is a voltage-controlled current source, the total RT pin current is the sum of all

of the parallel current sources connected to that pin. 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 current due to the RT resistor.
