  • Determining MOSFET Driver Needs for Motor Drive Applications
    driver is normally in the form of a power transistor. This can be a bipolar transistor, MOSFET or an Insulated Gate Bipolar Transistor (IGBT). In some small Brushless DC motor or stepper motor applications, the MOSFET driver can be used to directly drive the motor. For this application note, though
