Avago Technologies, a supplier of analog interface components for communications, industrial and consumer applications, has announced two new sets of high speed gate drive optocoupler devices, the ACPL-P/W347 and ACPL-P/W349.

These devices are 1.0A and 2.5A gate drive optocouplers designed to protect and drive fast switching next generation power semiconductors like the Silicon Carbide (SiC) and Gallium Nitride (GaN) MOSFETs and IGBTs in applications such as power inverters, motor drives, and switching power supplies (SPS). Compared to Avago’s previous generation devices, the ACPL-P/W347 and ACPL-P/W349 support wider gate operating voltage up to 30 V enabling higher voltage drive for high power applications.

Product Highlights

• 110ns Maximum Propagation Delay

• Wide Operating VCC Range: 15 to 30 V

• Rail-to-rail Output Voltage

• 2.5A Maximum Peak Output Current (ACPL-P/W349)

• 1.0A Maximum Peak Output Current (ACPL-P/W347)

• Under Voltage Lock-Out (ULVO) with Hysteresis

• 50kV/µs Minimum High Common Mode Rejection (CMR)

• Small Stretched SO6 Package Minimising PCB Board Space and Cost

• Safety Approvals for CSA, UL and IEC

o IEC/EN/DIN EN 60747-5-5: VIORM = 891 VPEAK (ACPL-P347/349), VIORM = 1,140 VPEAK (ACPL-W347/349)

o UL1577: VISO = 3,750 VRMS (ACPL-P347/349), VISO = 5,000 VRMS (ACPL-W347/349)

“As SiC and GaN MOSFETs gain market adoption and expand into higher power industrial applications, higher performance gate drive optocoupler devices like the Avago ACPL-P/W347 and ACPL-P/W349 ideally complement these fast switching power semiconductors in delivering maximum power conversion efficiency,” said Kheng-Jam Lee, marketing director of Avago’s Isolation Products Division.
