A316J IGBT DRIVER
F provide the large transient currents necessary during a switching transition. Because of a316j igbt transient nature of the charging currents, a low current 5 mA power supply suffices. The desat diode and pF capacitor are the necessary external components for the fault detection circuitry. The gate resistor 10?

The open collector fault output has a passive 3. In this application, the IGBT gate driver will shut down when a fault is detected and will not resume switching until the microcontroller applies a reset signal. A316j igbt Application Circuit. See Figure This may be accomplished either by software control i. Timing Diagram. This device slowly discharges the IGBT gate to prevent fast changes in drain current that could cause damaging voltage spikes due to lead and wire inductance. The capacitance value can be scaled slightly a316j igbt adjust the blanking time, though a value smaller than pF is not recommended. If the IGBT is turned on while the collector and emitter are shorted to the supply rails switching into a shortthe soft shut-down sequence will begin after approximately 3?
The recommended pF capacitor should provide adequate blanking as well as fault response times for most applications. At a316j igbt voltages below 13 V typically, their on-voltage increases dramatically, especially at a316j igbt currents. At very low gate voltages below 10 Vthe IGBT may operate in the linear region and quickly overheat.
Input IC In the normal switching mode, no output fault has been detected, and the low state of the fault latch allows the input signals to control the signal LED. The fault output is in the open-collector state, and the state of the Reset pin does not affect the control of a316j igbt IGBT gate. Tell us little more about your requirement.

The IGBTs become damaged when the current load approaches the saturation current of the device, and the collector to emitter voltage rises above the saturation voltage level. The drastically increased power dissipation very quickly overheats the power device and destroys it.
