ACPL-339J

ACPL-339J Dual-Output Gate Drive Optocoupler Interface with Integrated (VCE) DESAT Detection, FAULT and UVLO Status Feedback Data Sheet Description The ACPL-339J is an advanced 1.0 A dual-output, easy-touse, intelligent IGBT and Power MOSFET gate drive optocoupler interface. Uniquely designed to support MOSFET buffer of various current ratings, the ACPL-339J makes it easier for system engineers to support different system power ratings using one hardware platform by interchanging the MOSFET buffers and power IGBT/MOSFET switches. These changes can be made without redesigning the critical circuit isolation and short-circuit protection. This concept maximizes gate drive design scalability for motor control and power conversion applications ranging from low to high power ratings. The ACPL-339J contains a AlGaAs LED. The LED is optically coupled to an integrated circuit with two power output stages with active timing control to prevent cross conduction at external MOSFET buffer. It is also integrated with features such as VCE detection, under voltage lockout (UVLO), “soft” IGBT turn-off, and isolated open collector fault feedback to provide maximum design flexibility and circuit protection. The ACPL-339J has an insulation voltage of VIORM = 1414 Vpeak in IEC/EN/DIN EN 60747-5-5.
