Avago Technologies announced it has developed two gate drive optocouplers in Stretched Small Outline (SSO) packages for AC and DC brushless motors used in home appliances and industrial applications.

Avago's ACPL-W302 and ACPL-W314 gate drive optocouplers are suitable for controlling variable-speed brushless motors in energy-efficient home appliances such as air conditioners and washing machines. Other applications include small- to medium-sized motors used for industrial equipment, switching power suppliers and inverters.

The package size for the new optocouplers is 50 percent smaller and substantially thinner than conventional dual-inline packages. These optocouplers provide up to 8mm creepage and clearance to meet IEC, UL and CSA reinforced safety and insulation regulatory requirements. The creepage and clearance specifications of these SSO 6-pin (SSO6) packages make them suitable for safety-critical applications.

"Industrial equipment and home appliances are being made more compact, which means they require smaller electronic assemblies that meet international standards for reinforced electrical isolation," said Kheng-Jam Lee, worldwide marketing manager for isolation products in Avago Technologies' Optical Communication Solutions Division.

Performance characteristics of these optocouplers include 0.7s maximum propagation delay and a wide 10-30V (Vcc) operating range, both over the full temperature range and 3mA maximum supply current. These optocouplers are Pb-free and a RoHS compliant option is available.

The ACPL-W302 0.4 A peak and ACPL-W314 0.6 A peak isolated gate drive optocouplers in SSO6 packages are priced at 99 cents and $1.15 each, respectively, in 10,000-piece quantities. Samples and production quantities are available through Avago's sales network.
