Material Group (DIN VDE 0110, 1/89, Table 1). All Broadcom data sheets report the creepage and clearance inherent to the optocoupler component itself. These dimensions are needed as a starting point for the equipment designer when determining the circuit insulation requirements. However, once mounted on a printed circuit board, minimum creepage and clearance requirements must be met as specified for individual equipment standards. For creepage, the shortest distance path along the surface of a printed circuit board between the solder fillets of the input and output leads must be considered (the recommended Land Pattern does not necessarily meet the minimum creepage of the device). There are recommended techniques, such as grooves and ribs, that may be used on a printed circuit board to achieve desired creepage and clearances. Creepage and clearance distances will also change depending on factors, such as pollution degree and insulation level.

Based on BCDMOS technology, this gate drive optocoupler delivers higher peak output current, better rail-to-rail output voltage performance and faster speed than the previous generation products. The high peak output current and short propagation delay are needed for fast IGBT switching to reduce dead time and improve system overall efficiency. Rail-to-rail output voltage ensures that the MOSFET’s gate voltage is driven to the optimum intended level with no power loss across the MOSFET. This helps the designer lower the system power, which is suitable for bootstrap power supply operation. The ACNU-3410 has a VE pin that allows of use negative power supply without affecting the UVLO monitoring the positive power supply. It has very high CMR (common mode rejection) rating which allows the microcontroller and the MOSFET to operate at very large common mode noise found in industrial motor drives and other power switching applications. The input is driven by direct LED current and has a hysteresis that prevents output oscillation if insufficient LED driving current is applied. This will eliminates the need of additional Schmitt trigger circuit at the input LED. Recommended Application Circuit The recommended application circuit shown in Figure 16 illustrates a typical gate drive implementation using the ACNU-3410. The supply bypass capacitors provide the large transient currents necessary during a switching transition. Because of the transient nature of the charging currents, a low current (5.0 mA) power supply will be enough to power the device. The split resistors (in the ratio of 1:1.5) across the LED will provide a high CMR response by providing a balanced resistance network across the LED. Connect pin 1 and pin 4 to LED common. The gate resistor RG serves to limit gate charge current and controls the IGBT switching times. In PC board design, care should be taken to avoid routing the IGBT’s collector or emitter traces close to the ACNU-3410 input as this can result in unwanted coupling of transient signals into ACNU-3410 and degrade performance.
