Hi,
I am trying to use the 10 Amp H-Bridge to drive two motors. I haven't been able to get a test motor to operate, and I am not sure about the connections because I can't find a datasheet.
12V: to positive 14 V power supply
GND: to negative 14 V power supply
VCC: to positive 5V power supply
PWM1: 5 VPP Square wave, 50% duty cycle
DIR1: to positive 5V power supply
DIR2: Not connected
PWM2: Not connected
Enable: to positive 5V power supply
The motor doesn't seem to be getting an output from the H-Bridge. I tried to adjust the duty cycle between 25-80%, but the motor still doesn't move.
Is there a conventional setup/settings that work?
Thanks.

| Pull enable to 5V to enabme the H-bridge. Also make sure you have the grounds (logic and 12V) connected at some point. Ringo

| Thanks Ringo. Should the DIR and PWM be connected to the 5 VPP square wave?
