Low side vs. High side transistor switch Bald Engineer For an N Channel MOSFET, the source connects to ground, and the drain connects to the negative side of the load. While you can use a JFET for this circuit, an enhancement mode MOSFET works better. High side transistor switch. The opposite of the low side switch is the high side switch. This transistor connects between V and the load. Gate driver With the ability to place high voltage circuitry (in a ‘well’ formed by polysilicon rings) , that can ‘float’ 600 V or 1200 V, on the same silicon away from the rest of the low voltage circuitry, high side power MOSFETs or IGBTs exist in many popular off line circuit topologies such as buck, synchronous boost, half bridge, full bridge and three phase. MIC5021 High Speed, High Side MOSFET Driver with Charge Pump • Circuit Breaker General Description The MIC5021 high side MOSFET driver is designed to operate at frequencies up to 100 kHz (5 kHz PWM for 2% to 100% duty cycle) and is an ideal choice for high speed applications such as motor control, SMPS (switch mode power supplies), and applications using IGBTs. The MIC5021 can also operate as a circuit MOSFET IGBT DRIVERS THEORY AND APPLICATIONS especially when compared to an equally rated high volt age MOSFET. As far as driving IGBT is concerned, it resembles a MOS FET and hence all turn on and turn off phenomena com ments, diagrams and Driver circuits designed for driving MOSFET apply equally well to an IGBT.
