• Includes under-voltage lockout (UVLO) with hysteresis for reliable operation monitoring.
• Provides soft turn-off capability to reduce switching losses and electromagnetic interference.
• Features isolated collector-open fault feedback for real-time status indication.

Applications

• IGBT gate driving in motor control inverters
• Power conversion systems requiring high isolation
• Industrial drive applications
• Inverter circuits for renewable energy systems

Procurement Notes

Verify the specific suffix 'J' and '500E' against the manufacturer's latest datasheet to confirm pinout compatibility and functional specifications. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the part number with official Broadcom distributors to avoid counterfeit components. Confirm that the SOIC-16 narrow package dimensions match the target PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when a higher peak output current of 2.5 A is required compared to lower-current variants like the ACPL-330J. Consider the integrated protection features such as active Miller clamp and UVLO for robust designs. Evaluate the thermal performance given the 600 mW power dissipation limit in the SOIC-16 package. Ensure the system operating voltage and isolation requirements align with the 5000 Vrms rating.
