Short-Circuit Protection
The SCALE-iDriver uses the semiconductor desaturation effect to detect short-circuits and protects the device against damage by

employing an Advanced Soft Shut Down (ASSD) technique. Desaturation can be detected using two different circuits, either with R R VCE VCEX

DES The V level is optimized for IGBT applications. As soon as V >V DES CE DES (red circle in Figure 11), the driver turns off the power semiconductor switch with a control ed col ector current slope, limiting the V CE PI-7952-080416 overvoltage excursions to below the maximum col ector-emitter voltage (V ). Turn-on commands during this time and during t CES SO Figure 9. Short-Circuit Protection using Resistors Chain R . are ignored, and the SO pin is connected to GND. VCEX The response time t is the C charging time and describes the and power-down. Any supply voltage related to VCC, VISO, VEE and RES RES delay between V asserting and the voltage on the VCE pin rising VGXX pins should be stabilized using ceramic capacitors C , C , C , CE 1 S1X S2X (see Figure 11). Response time should be long enough to avoid false C respectively as shown in Figures 13 and 14. After supply GXX tripping during semiconductor turn-on and is adjustable via R and voltages reach their nominal values, the driver will begin to function RES C (Figure 10) or R and C (Figure 9) values. It should not be after a time delay t . RES VCE RES START longer than the period al owed by the semiconductor manufacturer.
Short-Pulse Operation Safe Power-Up and Power-Down
If command signals applied to the IN pin are shorter than the minimum During driver power-up and power-down, several unintended input / specified by t , the SCALE-iDriver output signals, GH and GL pins, GE(MIN) output states may occur. In order to avoid these effects, it is will be extended to value t . The duration of pulses longer than GE(MIN) recommended that the IN pin is kept at logic low during power-up t will not be changed.
