OUT1 Motor drive output pin.

1

OUT2 Connect the Schottky diode between the output -

2

OUT2

VCC.

3

GND2 Output GND pin.

5

VM

Power and output current detection pins of the

output. Connect a low resistance (Rf) between this

pin and VCC.

The output current is limited to the current value set

with IOUT = VRF/Rf.

VCC

VCC

Power pin (Other than the output).

6

VREG Stabilized power supply output pin (5V output).

Connect a capacitor (about 0.1μF) between this pin

and GND for stabilization.

PWM

Pin to set the PWM oscillation frequency.

VREG

Connect a capacitor between this pin and GND.

This can be set to about 18kHz with C = 3900pF.

circuit.

Connection of a capacitor (about 10μF) between

CSD and GND can set the protection operation time

of about 3.3seconds.
