5. Output-VCC short, output-GND short and over voltage detecting pin(8)
In case of such abnormalities as output-VCC short, output-GND short, overvoltage (Fig.9), it is possible to
inform the abnormal state to the outside by turning a NPN transistor is turned on.
It is possible to improve the reliability of not only power IC but also an entire equipment by (1) display by LED
and LCD and (2) by turning the power supply relay off.
6. Stand-by SW function
By means of controlling pin(1) (stand-by terminal) to high and low, the power supply can be set to on and off.
The threshold voltage of pin(1) is set at about 3VBE≒2.1V (typ.), and the power supply current is about 1A
(typ.) at the stand-by state.
Control voltage of (1)pin: V (SB)
