  • Determining MOSFET Driver Needs for Motor Drive Applications
    Electronic motor control for various types of motors represents one of the main applications for MOSFET drivers today. This application note discusses some of the fundamental concepts needed to obtain the proper MOSFET driver for your application. The bridging element between the motor and MOSFET
  • Matching MOSFET Drivers to MOSFETs
    There are many MOSFET technologies and silicon processes in existence today, with new advances being made every day. To make a generalized statement about matching a MOSFET driver to a MOSFET based on voltage/current ratings or die sizes is very difficult, if not impossible. As with any design
  • Universal Power MOSFET Interface IC (TC4420/9)
    The TC4420/4429 are 6A high-speed MOSFET drivers available in an 8-pin SOIC package, 8-pin CerDIP and PDIP packages, and a 5-pin TO-220 package. These parts have additional improvements over the TC429 driver. Added features are 4kV of ESD protection, latch-up protection of >1.5A of reverse output
  • A Digital Constant Current Power LED Driver
    AN1138 A Digital Constant Current Power LED Driver drive current for this type of LED would be 350 mA and Author: Stephen Bowling a typical forward voltage would be 3.5V. Secondly, we Microchip Technology Inc. will assume that the circuit input voltage is 12V. The inductor value will be chosen
  • Design Considerations in Using the Inverter Gate Driver Optocouplers for Variable Speed Motor Drives - White Paper (.pdf)
    Inverter Gate Driver optocouplers are ideally suited for IGBT and MOSFET applications for variable speed motor drives. Their high output peak currents coupled with high voltage safety standards certified galvanic insulation, very high common mode noise rejection isolation, solid state device level
  • Galvanic isolation for IGBT-Driver
    applications in the high power range, the complexity of the IGBT control circuit is in fact much higher than in the case of the control of a small MOSFET.
  • Soft-Start Controller For Switching Power Supplies
    driven by the power supply is capacitive, the problem is exaggerated due to the large transient currents required to charge the capacitive load. In extreme instances, the repeated high stress of start-up can result in catastrophic failures in the driver section, typically, the power MOSFET transistors
