DESCRIPTION
Power supply pin. A function for protection against over-voltage is provided so that the output will turn off when the applied voltage exceeds 27.5V (Typ.). This function works to protect the IC and load.
PNP-type complementary output pin with a current capacity of 1.5A. When the output pin is supplied with a current exceeding the detection current (typically 3A) because of load short-circuit, the output is latched to the OFF state to protect the IC. To restart, turn off the input once, then raise it high.
Self-diagnosis detection pin. This signal goes low when the output is short-circuited or opened while the input is on (high). The output will be latched when ...
