DESCRIPTION
Power supply pin. This pin has a function to turn off the output when the applied voltage
exceeds 30V (Typ.), thus protecting the IC and the motor load.
When this pin is opened or grounded, the output turns off, thus reducing the current
consumption to 100µA or less. If standby mode is not needed, the pin is connected to VCC.
This is input terminal which controls output condition of pin 4 and pin 5.PNP-type voltage
comparator is built in.
PNP-type complementary output pin with a current capacity of 1.5A. This pin is controlled by the
input from pin 3. When the output is supplied with a current exceeding the detection current (4A
Typ.) because of load short-circuit, the output is latched to the OFF state after a 50µs (Typ.)
delay in order to protect the IC.
Output pin of the inversion of pin 4. This terminal has the same function as pin 4 and is
controlled by pin 3.
Ground terminal of output section which is usually connected with pin 11.
Not connected. (Electrically, this pin is completely open.)
Output pin of the inversion of pin 9. This terminal has the same function as pin 4 and is
controlled by pin 10.
This terminal has the same function as pin 4 and is controlled by pin 10.
This is input terminal which controls output condition of pin 8 and pin 9.PNP-type voltage
comparator is built in.
Ground terminal of logic control section which is usually connected with pin 6.
Self-diagnostic output pin. This signal goes low when the output is short-circuited while the input
is on (high). The output will be latched after a 50µs (Typ.) delay when the load is
short-circuited.This pin supplies an NPN open-collector output.
