H-Bridge has been designed around IR2104 IC from international Rectifier. The board has been made mainly for DC-Motor application. The driver can handle load up to 8-10Amps. I have tested this board with 36V DC supply . The circuit uses N Channel IR540 MOSFETS from international rectifier. IR540 requires large heat sink for 10Amps load. Board has shunt resistor to provide voltage proportional to current flowing through load. This can be later amplify and connect it to microcontroller.

Features

Motor DC Supply 36V DC (Screw Terminal Connector)
Logic Supply 12V DC
Load 8-10Amps (Screw Terminal Connector)
Header Connector for Inputs (7 Pin Header Connector)
On Board Shunt Resistor for Current feedback
PWM Frequency 10 to 20 KHz
Duty Cycle 0-99%
Logic Pins support 3.3V, 5V, 12V (Inputs and PWM)
