    VDD2, LED current (IF) and overcurrent (OC) conditions. For the details related to the logic truth table of these outputs, refer to the ACPL-352J data sheet. The driver provides an ideal solution combining local overcurrent detection (OC), soft shutdown (SS) with high-speed current output and highp-voltage optical isolation.

The OC terminal monitors the voltage between the collector and the emitter (V ) of the IGBT. When this voltage exceeds 9V, the output voltages (VOUTP and VOUTN) go to high impedance state and the SS pulls down the VGATE at a slow rate adjustable using the resistor.

    4A. The next step in choosing the correct gate resistor is to check the power dissipation of the ACPL-352J gate driver. If the power dissipation is too high, the resistance of the gate resistor should be increased. For detailed instructions on choosing the gate resistor, refer to the ACPL-352J data sheet.
