Gate Drive Optocoupler

Highly Integrated Solution Minimizes PCB Space and Delivers High Performance

By combining optocoupler technology with a 5.0 A power transistor into a single 8-pin wide-body package, Avago's ACNW3190 delivers a high output current gate optocoupler driver which minimizes PCB space, offers component savings and lower design costs and provides high CMR noise isolation.

Ideal for AC/DC motor drives, industrial inverters and inverter controller home appliances, the ACNW3190 adds UVLO to prevent insufficient gate voltage from turning on the IGBT leading to power loss across it. The optocoupler is also optimized for high power applications by offering good noise immunity with superior common mode rejection rate of 15 kV/μs at 1,500 V. Additionally, Avago's ACNW3190 supports temperatures up to 100 °C at the maximum 5.0A output current level.

The highly integrated ACNW- 3190 is available in an easyto- use 8-pin widebody packaging with 10mm creepage and clear-ance. The product satisfies all major opto-isolation safety standards, such as UL, CSA, IEC/EN/DIN EN 60747-5-2.
