The new devices include rail-to-rail output voltage, an integrated LED driver, an active Miller clamp, an empty DESAT current source, and a low voltage lockout feedback control circuit (ULVO), and offer a complete and cost-effective solution for gate drives for motor control applications and power inverter applications.
“To meet the power and efficiency requirements of modern applications, the complexity of door drive device design continues to increase. Customers who have used Avago’s proven HCPL-316J device are demanding a higher level of chip integration of the door drive’s functional blocks,” commented Kheng-Jam Lee, Marketing Director of Avago’s Isolation Products Division. “The new APCL-336J and ACPL-337J devices not only reduce the number of external components required for door drives, but also set a new standard for compact door drive optocoupler solutions for motor drives and inverters.”.
Product Highlights of ACPL-336J/ACPL-337J
- High-current rail-to-rail output voltage eliminates the output buffer stage and improves energy efficiency.
- Integrated LED drive, active Miller clamping, and an empty DESAT current source reduce system costs and board space.
- Integrated short-circuit protection and FAULT and UVLO feedback control circuitry improve system reliability for driving and protecting the IGBT.
- Highly reinforced insulation voltage of VIORM=1414VPEAK for reliable fail-safe protection in high-voltage applications.
- A large creepage distance and 8.3 mm clearance meet narrow system-level safety regulations.
- Typical high CMR of 50kV/µs prevents erroneous operation in noisy environments.
- CSA, UL, and IEC safety approvals enable rapid system-level safety accreditation and time to market.
