Half bridge control IC for CCFL backlighting
The signal from the IC is a voltage signal and the signal to the IC is a current signal. In this
way a driving con?ict is prevented. Also, it leaves the possibility for the outside world to
see the signal from the IC even while a fault condition is being signalled to the IC in the
meantime, as illustrated in Figure 18 .

8.14.10 Fault input via the COMM pin
If a fault is signalled to the IC via the COMM pin this fault is treated identical to hard
switching detected, see Section 8.14.3 .

In accordance with the Absolute Maximum Rating System (IEC 60134). All voltages are measured with respect to signal
ground (SGND pin 10).
