Frame

GND

Frame GND.

GND must be shared.

GND

UOUT

VOUT

WOUT

Output pins.

Motor connection

Output Tr GND.

A resistor can be connected between this pin

and GND to sense the output current as a

voltage drop to provide for overcurrent

protection.

18, 24

Idle pins.

VCC2

4.3 to 6.5 V

v Power supply for blocks other than the

output block.

v This supply should be kept stable to

prevent ripple and noise from entering this

pin.

v First-stage amplifier gain setting resistors.

v Z1 and Z2 normally range from several

tens of k

Ω to several hundreds of kΩ.

v The gain is about 6 dB.

VCref

VCC2/2

±1.0

v VC is the speed control pin.

Forward when VC > VCref.

Reverse when VC < VCref.

VC is used to control the output voltage.

v VCref determines the motor control stop

voltage.

VCC2/2 in normal use.

GC1

GC2

0toVCC2

v Input/output gain switching pins.

v GC1 is for first-stage amplifier Z1/Z2

switching.

When GC1 is LOW, Z1 is selected;

when HIGH, Z2 is selected. GC2 is for

next-stage amplifier switching.
