Motor drive output pin.
Connect the Schottky diode between the output -
V CC .
Output GND pin.
Power and output current detection pins of the
output. Connect a low resistance (Rf) between this
pin and V CC .
The output current is limited to the current value set
with I OUT = V RF /Rf.
Power pin (Other than the output).
Stabilized power supply output pin (5V output).
Connect a capacitor (about 0.1μF) between this pin
and GND for stabilization.
Pin to set the PWM oscillation frequency.
Connect a capacitor between this pin and GND.
This can be set to about 18kHz with C = 3900pF.
Pin to set the operation time of motor lock protection
circuit.
Connection of a capacitor (about 10μF) between
CSD and GND can set the protection operation time
of about 3.3seconds.
