tSF: Sweep Frequency time. This time is given by the RC network built with CSWEEP and RPH.
tSK: Sweep sequence recycle time. This time is derived by integrating a constant DC current in capacitor
CPH. There is a fixed ratio ( ) between the preheating time tPH and strike sequence recycle time tSK.
tfEND: Time during which f = (fENDSWP). This time is equal to tSK – tSF.
The controller repeats the fSWEEP and the strike sequence until there is a STRIKE signal comng fromthe external circuit, or until FOUR sequences have been counted.
Following a non strike situation, the controller goes in a full STOP and can be reinitialized by either pulling the VDD pin 1 to ground or by forcing a low to the RESET
pin 9. The controller assumes the lamp has struck when a negative going transient is applied on the STRIKE detection pin 10. On the other hand, in order to avoid false
strike information, the controller force a blank time between the end of tSWEEP and the start of the next sequence.
