element14 Pty Ltd has added the highly-integrated gate drive optocouplers from Avago Technologies, designed to provide a complete cost-effective solution for motor control and power inverter applications where the MCU needs to be isolated from high voltages.
Avago is a world-leading supplier of analogue interface components for wireless, wireline and industrial applications.
Avago’s optically-isolated devices are optimised for driving high power MOSFET or IGBT directly, exhibiting fast gate switching speed, minimal propagation delay, high CMR and reinforced insulation.
Key features of the Avago APCL-336J and APCL-337J gate drive optocouplers include 2.5A and 4A rail-to-rail output with high current respectively; integrated short circuit protection with feedback; integrated LED driver; active Miller clamp; high DESAT blanking current source; and Under Voltage Lock-out (ULVO) feedback control circuit.
Avago’s gate drive solutions offer key benefits such as significantly reduced system costs and board space, as well as improved overall power efficiency and reliability.
According to Marc Grange, Head of Product Marketing, element14 Asia-Pacific, the Avago devices set a new standard for compact gate drive optocoupler solutions, and suit the needs of element14 customers who demand a higher level of on-chip integration for their next-generation applications.
