The first prototype of the design (on a semi-homemade PCB), Top viewĪfter reading this article, you are 100% sure about the true operation of the circuit. I just used a semi-homemade PCB board to be able to quickly assemble the board and test the circuit (figure-5). So let’s construct and build the circuit. The 3D view improves the inspection procedure of the board and component placement. Selected component libraries for the IR2104 and IRFN150Nįigure-4 shows a 3D view of the PCB board. Because I used Altium Designer to draw the schematic and PCB, I directly used the SamacSys Altium plugin (figure-3). You can either use the “component search engine” or a CAD plugin. Therefore I use the SamacSys provided symbols, instead of wasting my time and designing the libraries from scratch. I did not have the PCB footprint and schematic symbols of IR2104 and IRFP150 components. It is designed in a way to reduce the noise and transient to help the stability of the device.ĭesigned PCB layout for the motor driver schematic The PCB layout of the schematic demonstrated in figure-2. You must inject your PWM pulse to the IN pin as well. Then you must apply a steady state logic level voltage to this pin to activate the chip. The SD pin has pulled down with a 4.7K resistor. If you are sure that your load voltage does not pass a threshold (for example a 12V DC motor), then you can decrease the voltages of the capacitors to 25V for instance and increase their capacitance values instead (for example 1000uF-25V). So I used 100V rated capacitors at least. The maximum tolerable MOSFETs voltage is 100V. The capacitors C1 and C2 are used to reduce the motor’s noise and EMI.

That’s the reason why MOSFET drivers like IR2104 are useful. There is no problem with the high input capacitance of the IRFP150 MOSFETs. The IR2104 drives the MOSFETs in a half-bridge configuration. The floating channel can be used to drive an N-channel power MOSFET or IGBT in the high side configuration which operates from 10 to 600 volts.” The output drivers feature a high pulse current buffer stage designed for minimum driver cross-conduction. The logic input is compatible with standard CMOS or LSTTL output, down to 3.3V logic. Proprietary HVIC and latch immune CMOS technologies enable ruggedized monolithic construction. The schematic diagram of the powerful DC motor driverĪccording to the IR2104 datasheet : ”The IR2104(S) are high voltage, high-speed power MOSFET and IGBT drivers with dependent high and low side referenced output channels. The schematic diagram of the circuit demonstrated in figure-1. It is a popular and applicable MOSFET driver IC. The heart of the circuit is an IR2104 MOSFET driver chip. By using a proper heatsink and cooling methods, this circuit can handle currents up to 30A.

You can control it using a Microcontroller, an Arduino, a Raspberry Pi or even a standalone PWM generator chip. In this article, we will learn to build one. Therefore there is wide usage and request for suitable and powerful DC motor drivers. DC motors are everywhere, from hobby applications to robotics and industrial areas.
