PRECATION(1) Confirmation of gate average current
The maximum rating
g of output
p current capacitypyp
per one circuit of the ggate ppower supply
pp y built-in this pproduct is 100mA.

And the steady-state consumption current of the gate driver is about 10mA. Therefore the gate average current
must be less than 90mA.
Please calculate the gate average current by the following expression.
Idrive = (Q1＋lQ2l ) X f
Idrive : Gate average current
Q1 : Gate charge on plus bias (Please read it from data sheet of IGBT)
Q2 : Gate charge on minus bias (Please read it from data sheet of IGBT)
f: Switching frequency(2) Electric power setting of gate resistanceAt the time of the choice of gate resistance, please choose the resistance which can permit the electric power by the following calculation.
Pd = Idrive X 24
Pd: Total allowable power loss of gate resistance
Idrive : Gate average current
24: Total output voltage of gate power supply
