Half-Bridge Current Sensing and Protection
The third pin used for protection is the CS pin, which is nor-
mally connected to a resistor in the source of the lower power
MOSFET, as shown in Figure 16. The CS pin is used to
sense fault conditions such as failure of a lamp to strike,
over-current during normal operation, hard switching, no load,
and operation below resonance. If any one of these condi-
tions is sensed, the fault latch is set, the oscillator is dis-
abled, the gate driver outputs go low, and the chip is put into
the micropower mode. The CS lead performs its sensing
functions on a cycle-by-cycle basis in order to maximize
ballast reliability.
For the over-current, failure-to-strike, and hard switching fault
conditions, an externally programmable, positive-going CS+
threshold is enabled at the end of the preheat time. The level
of this positive-going threshold is determined by the value of
the resistor ROC. The value of the resistor ROC is determined
by the following formula:

Half-bridge current sensing circuit connection
(shaded area)
For the under-current and under-resonance conditions, there
is a negative-going CS- threshold of 0.2V which is enabled
at the onset of the run mode. The sensing of this CS-
threshold is synchronized with the falling edge of the LO
output.
Figures 17, 18 and 19 are oscillographs of fault conditions.
Figure 17 shows a failure of the lamp to strike, Figure 18
shows a hard switching condition and Figure 19 shows an
under-current condition.
