Connect a DC motor (R
L
= R
) between OUT1 and OUT2, and with the RD pin pulled up, input a forward rotation signal
(IN1 = high, IN2 = low).
Because the output is used in the saturated state at startup, set the DEL input to low.
The DC motor starts up, and the startup current (I
ST
= V
M
/R) flows to the motor.
The DC motor rotates in the normal state. At this point, set the DEL input to high.
If the DC motor locks, the motor current I
M
increases to the point of I

to limit the output current. At the same time, RD is output low from the set current detection circuit.
