San Jose, Calif. Avago Technologies has launched two gate drive optocouplers in stretched small outline (SSO) packages for AC and DC brushless motors used in home appliances and industrial applications. The ACPL-W302 and ACPL-W314 gate drive optocouplers are suited 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.
At half the size of conventional dual-inline packages, the six-pin SSO (SSO6) packaged optocouplers provide up to 8 mm of creepage and clearance to meet stringent IEC, UL and CSA reinforced safety and insulation regulations. These specifications make them suitable for safety-critical applications. (Creepage is a spacing distance measured over a surface, such as the surface of an optocoupler. Clearance is the shortest distance through air, such as between pins of an optocoupler.) Approvals to the following safety standards are pending: IEC/EN/DIN EN 60747-5-2 (Option 060 only), UL 1577, and CSA Component Acceptance Notice #5, File CA 88324.
The ACPL-W302 (0.4 A peak) and ACPL-W314 (0.6 A peak) isolated gate-drive optocouplers feature 15 kV/microsecond minimum common mode transient immunity at 1000 V common-mode voltage (VCM) and operate in the -40°C to 100°C temperature range. The devices offer a wide 10 V to 30 V (VCC) operating range and a 0.7 microsecond maximum propagation delay over the operating temperature range. The maximum supply current is 3 mA. These devices are available in lead-free and RoHS-compliant options. Click the link for more information about Avago's optocouplers.
The ACPL-W302 0.4 A peak and ACPL-W314 0.6 A peak isolated gate drive optocouplers are priced at $0.99 and $1.15 each, respectively, in quantities of 10,000.
