Function
1OSC
An external capacitor to ground fixes the half-bridge switching frequency with a
± 3 % precision.
2RF
Voltage reference capable of sourcing up to 240 A. The current sunk from this
pin fixes the switching frequency of the half-bridge for each operating state.
A resistor (
RRUN) connected to ground sets the half-bridge operating frequency
combined with the capacitor connected to the pin OSC.
A resistor connected to EOI (RPRE) sets the maximum half-bridge switching
frequency during preheating combined with
RRUN and COSC.
3EOI
Connected to ground by a capacitor that, combined with RPRE, determines the
ignition time.
Preheating: low impedance to set high switching frequency
Ignition and run mode: high impedance with controlled current sink in case of
HBCS threshold triggering.
