1.3 Power supply sequence and derating for VCC
Power supply sequence of power-on should be VCC on, next VS on and control signal
VSP on. For power-off, it should be controlled signal off, next VS off and VCC off.
If the control signals VSP is low, the power supply sequence is free.
In case of above sequence can not control such as suddenly stopped the power supply,
It should be taken the following.
When IGBTs operated with lower gate voltage, it will be occurred the thermal failure
because IGBT saturation voltage increase rapidly, especially VCC voltage period is
VCCop minimum value to LVSDON minimum value, that is 13.5V to 10V.
To avoid this mode, refer derating curve of VCC in figure 6 .

1.4 Derating for maximum allowable ratings
Derating design standards is below.
a) Temperature ; Junction temperature must be kept under 110
oC.
b) Voltage
; VS power supply voltage must be kept under 185V.
