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 the load is short-circuited, but will
not when the load is opened. This pin supplies an NPN open-collector output.
TTL-compatible input pin. The circuit is shown as follows.
