Gate drive optocoupler minimizes PCB space

San Jose, Calif.—Avago Technologies is offering the ACNW3190, a high output current gate drive optocoupler with under voltage lockout (UVLO).

The ACNW3190 combines optocoupler technology with a 5-A power transistor into a single 8-pin package. According to Avago, the ACNW3190 minimizes PCB space, lowers design costs, and provides high CMR noise isolation.

Aimed at 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 and lead to power loss across it. The optocoupler is also optimized for high power applications by offering high noise immunity with common mode rejection rate of 15kV/µs at 1500V. Additionally, the ACNW3190 supports temperatures up to 100°C at the maximum 5.0A output current level.

The ACNW3190 is available in an 8-pin package and in a widebody packaging with 10 mm creepage and clearance. The product satisfies all major opto-isolation safety standards, such as UL, CSA, IEC/EN/DIN EN 60747-5-2.

Pricing: $2.03 in 10,000-piece quantities.
Availability: Through Avago's direct sales channel and worldwide distribution partners.
