Note In operating the thermal shutdown, the status of output-pin is OFF.
In this case, however, if CTL-pin is kept non-active level, this IC isn’t in stand-by mode.
And, thermal shutdown circuit can not be operated in both CTL1-pin and CTL2-pin are non-active
level (equal to stand-by mode), if junction-temperature of this IC exceed 150 degree (typ.).
