San Jose, Calif. Avago Technologies has introduced the ACPL-312T gate drive optocoupler targeting automotive hybrid electric vehicle applications. Designed to meet automotive AEC-Q100 guidelines, the ACPL-312T provides 2.5-A maximum peak output current to drive high powered IGBTs/MOSFETs and operates up to a high temperature rating of 125°C. In addition, a propagation delay of 0.5 us allows the circuit designer to reduce switching dead time and improve inverter efficiency, Avago said.
The ACPL-312T optocoupler leverages an automotive-grade LED that was developed and produced in-house. The gate drive optocoupler offers an enhanced construction, which is said to provide superior thermal conductivity, making it suitable for isolation needs in automotive, industrial inverters and power management applications over the operating temperature range of -40°C to 125°C. It also offers high CMR (min 25 kV/us @ VCM = 1500V), which makes it well-suited for noise elimination, and provides under voltage lockout (UVLO) for additional product protection.
In addition to automotive requirements, the ACPL-312T optocouplers meet worldwide safety standards (UL1577, EN/IEC 60747-5-2 and CSA).
The ACPL-312T will be showcased at the PCIM conference, Nuremberg, Germany, in booth number 126, May 27-29.
Pricing: Starts at $1.88 each in quantities of 10,000.
