Supply Voltage:
•
•
•
VCC (2.5 to 5.5V): Control voltage Supply for LSI
VM (2.5 to 5.5V): Power Supply for LSI
VC( 0 to VCC ):Constant voltage control setting
Testing Procedure for DC Motor Control:
1. Motor Connection: Connect the Motor(s) between OUT1 and OUT2.
2. Power Supply: Supply DC voltage to VCC, VM.
3. Motor Operation: Set EN and IN1 and IN2 terminals according to the purpose (See
LV8075LP datasheet).
