TREATMENT WITHOUT USING CSCP TERMINAL

When not using the timer-latch short-circuit protection circuit, connect the CSCP terminal (pin 8) to GND with
the shortest distance.

RESETTING THE LATCH OF EACH PROTECTION CIRCUIT

When the overcurrent, or short-circuit protection circuit detects each abnormality, it sets the latch to fix the output
at the "L" level.

To reset the actuated protection circuit, either the power supply turn off and on again or set the CTL terminal
(pin 24) to the "L" level to lower the VREF terminal (pin 17) voltage to 2.4 V (Min) or less.
