[owe [sao] meno Power supply pin. A function for protection against over-voltage is provided v, so that the output will turn off when the applied voltage exceeds 27.5V cc | typ). This function works to protect the IC and load. PNP-type complementary output pin with a current capacity of 1.54. When 211 out the output pinis 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- 3, 10 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. a7kQ 4,9 Sg When this signal goes high, both channels 1 and 2 are placed in standby state (0.5mA Max.).
