IGBT/MOSFET Gate Drive
The IRS2336xD HVICs are designed to drive up to six MOSFET or IGBT power devices. Figures 1 and 2 illustrate
several parameters associated with the gate drive functionality of the HVIC. The output current of the HVIC, used to
drive the gate of the power switch, is defined as I O . The voltage that drives the gate of the external power switch is
defined as V HO for the high-side power switch and V LO for the low-side power switch; this parameter is sometimes
generically called V OUT and in this case does not differentiate between the high-side or low-side output voltage.
