... The voltage and current supplied by these optocouplers make them ideally suited for directly driving IGBTs with ratings up to 1200 V and 150 A. For IGBTs with higher ratings, the ACPL-332J can be used to drive a discrete power stage which drives the IGBT gate. The ACPL-332J has an insulation voltage of V ...

... S SHIELD SHIELD Figure 35. Block Diagram of ACPL-332J Recommended Application Circuit The ACPL-332J has an LED input gate control, and an open collector fault output suitable for wired ‘OR’ ap- plications. The recommended application circuit shown in Figure 36 illustrates a typical gate drive implementa- tion using the ACPL-332J. The following describes about driving IGBT. However also applicable to MOSFET. ...

... Figure 36. Recommended application circuit (Single Supply) with desaturation detection and active Miller Clamp Description of Operation Normal Operation During normal operation the ACPL-332J is con- OUT trolled by input LED current IF (pins and 8), with the IGBT collector-to-emitter voltage being monitored through DDESAT. The FAULT output is high. See Figure 37. ...

... OFF X ON Not Active 21 Slow IGBT Gate Discharge during Fault Condition When a desaturation fault is detected, a weak pull-down device in the ACPL-332J output drive stage will turn to ‘softly’ turn off the IGBT. This device slowly discharges CC2 E the IGBT gate to prevent fast changes in drain current that could cause damaging voltage spikes due to lead and wire inductance. During the slow turn off, the large > ...

... Under Voltage Lockout The ACPL-332J Under Voltage Lockout (UVLO) feature is designed to prevent the application of insufficient gate voltage to the IGBT by forcing the ACPL-332J output low during power-up. IGBTs typically require gate voltages achieve their rated V At gate voltages below 13 V typically, the V increases dramatically, especially at higher currents. At very low gate voltages (below 10 V), the IGBT may operate in the linear region and quickly overheat ...

Pull-up Resistor on FAULT Pin The FAULT pin is an open collector output and therefore requires a pull-up resistor to provide a high-level signal. Also the FAULT output can be wire ‘OR’ed together with other types of protection (e.g. over-temperature, over- voltage, over-current ) to alert the microcontroller. Other Possible Application Circuit (Output Stage ...
