RPLLNR3
At the completion of the Ignition Ramp mode (beginning of the Run mode) the near/below resonance
(under-current) detection is also enabled. Near/below resonance detection is performed by synchro-
nously sensing the voltage across resistor RCS, which relates to the current flowing in the low side
MOSFET (MLS), just prior to the turn off of MHS. If this voltage is lower than the near/below reso-
nance threshold (CS- = 0.2V) of the CS pin of the IR2167, a lamp fault condition is signaled and the
ballast goes into Fault mode. This could occur if the frequency of oscillation becomes too close to the
resonant frequency of the load circuit and the current in the load circuit commutates to close to zero.
Figure 16 shows a near/below resonance condition where the voltage on resistor RCS falls below the
0.2V threshold on the CS pin of the IR2167.
Figure 16:
Near/Below Resonance conditions
Upper trace: voltage across RCS
Lower trace: half-bridge output voltage
The components REOL1 REOL2, REOL3, REOL4, CEOL, DEOL1 and DEOL2 are used for end of
life protection. The end-of-life window comparator is enabled at the beginning of the Run mode. If
the voltage on the lamp change +-20%, one of the zener diodes DEOL1 or DEOL2 will conduct and
the voltage on pin SD of the IR2167 will fall outside the range of the internal window comparator 1-
3V causing the IR2167 to go into Fault mode.
