Summary of DC Motor IR2104 H-BRIDGE
This project is an H-Bridge motor driver based on the IR2104 IC designed for DC motor control. It supports a 36V DC motor supply and can handle loads of 8-10 Amps using IR540 N-channel MOSFETs. The board includes a shunt resistor for current sensing, allowing feedback to a microcontroller. It operates with a logic supply of 12V and supports PWM frequencies from 10 to 20 kHz with duty cycles from 0 to 99%. Inputs support logic levels of 3.3V, 5V, and 12V.
Parts used in the H-Bridge motor driver project:
- IR2104 IC (International Rectifier)
- IR540 N-Channel MOSFETs (International Rectifier)
- Shunt resistor
- Screw terminal connector for DC motor supply (36V)
- Screw terminal connector for motor load (8-10 Amps)
- 7-pin header connector for inputs
- Logic power supply (12V)
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.
