2. About the operation of short-circuit protection at parallel synchronous operation
In the case of the operation in parallel, if the single output (or multiple outputs) of them is short-circuited and
the timer latch short circuit protection of the IC is operated, the output of other ICs will be also shut down, then
enter into latch mode.
In figure 8, if the IC-2 entered timer latch mode, Q1 turns on and the OSC terminal (pin 1) is fixed to
approximately 1.1 V and the oscillator stops.
Then channel 1 of IC-1 becomes low level than the DT1 terminal (pin 6) voltage or high-level voltage (0.9 V)
of the FB1 terminal set by terminal voltage, and then output 2 stops by PWM1 circuit of inside. The channel 2 stops
output 2 by oscillator high-level detection comparator.
And then, the IC-1 becomes short-circuit state and enters latch mode after a certain time.
It becomes the same operation in case of the IC-1 enters latch mode previously.
