(LIGN), capacitor (CIGN), resistor (RIGN2) and switch (MIGN). When the IC turns on the
switch MIGN, capacitor CIGN discharges through resistor RIGN2. When the voltage
across DIGN reaches the diac threshold voltage (Figure 5.4), DIGN turns on and a
current pulse flows from the buck output, through the primary winding of LIGN and into
capacitor CIGN. This arrangement generates a high-voltage pulse on the secondary to
ignite the lamp. The capacitor CIGN charges up until the diac turns off, and CIGN then
discharges down through resistor RIGN until the diac voltage again reaches the device’s
threshold and another ignition pulse occurs.

Figure 5.4: Ignition circuit timing diagram
The ignition circuit will continuously try to ignite the HID lamp for 21sec ‘on’ and 64sec
‘off’ until the lamp ignites. If the lamp does not ignite after 1180sec then the IC will enter
Fault Mode and latch off. If the lamp ignites successfully, the voltage at the VSENSE pin
will fall below VOV(2/5) due to the low impedance of the lamp and the ignition timer will
be disabled (logic ‘low’ at the IGN pin).
5.4 General Mode
During General Mode, the IC reacts to the different load conditions (open-circuit, short-
circuit, lamp warm-up, constant power running, under-voltage lamp faults, transient
under-voltage lamp faults, over-voltage lamp faults, lamp non-strike, etc.) by turning the
buck circuit on or off, adjusting the buck circuit on-time, or counting the occurrence of the
different fault conditions and turning the complete IC off. The IC senses the different
load conditions at the VSENSE and ISENSE pins, compares the voltages at these pins
against the programmed thresholds at the OV and OC pins, and determines the correct
operating mode of the IC (see State Diagram).
5.5 Full-Bridge Control
The IC includes a complete high and low-side full-bridge driver necessary for driving the
