2. Protection circuit
1) Timer
In control of this IC, the chopper circuit does not start unless the first on-signal is input to the switching
device. The chopper circuit does not re-start, if the turn-on timing of switching device is missed due to some
abnormality.
For the above reasons, this IC is incorporating the timer circuit and generating the start pulse once in
every approx. 400
μ
s (typical) when the chopper circuit stops, eliminating the need for an external part to cope
with this problem. (Refer to figure 9.) However, in order to prevent the output rise of the chopper circuit, the
timer circuit does not operate as long as the overvoltage protector is operating.
