and turn off the external output transistor to make dead time 100%. The circuit restores voltage supply when
the supply voltage reaches its threshold voltage.
(2) Timer-latch short-circuit protection circuit (SCP Comp., SR Latch)
The latch circuit detects the output voltage levels of the error amplifiers. When the output voltage levels of the
two error amplifiers reach about 2.1 V at the same time, the timer circuit is actuated to start charging the external
capacitor connected to the CSCP pin (pin 5). If the error amplifier outputs are not restored to the normal voltage
range before the capacitor voltage reaches about 0.7 V, the latch circuit is actuated to fix the output pins (OUT)
at the “H” level. To reset the actuated protection circuit, turn the power supply on back.
