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 6 and pin 7. 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 5. 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 6. This terminal has the same function as pin 6 and is
controlled by pin 5.
Ground terminal of output section which is usually connected with pin 17.
Output pin of the inversion of pin 15. This terminal has the same function as pin 6 and is
controlled by pin 16.
This terminal has the same function as pin 6 and is controlled by pin 16.
This is input terminal which controls output condition of pin 14 and pin 15. PNP-type
voltage comparator is built in.
Ground terminal of logic control section which is usually connected with pin 10.
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.
Not connected. (Electrically, this pin is completely open.)
