Avago Technologies yesterday announced the ACPL-P34x and ACPL-W34x family of gate drive optocouplers said to deliver high output peak current, rail-to-rail output voltage and fast switching speed.
Traditionally, Avago gate drive optocouplers have used bipolar transistors for the output stage to deliver high output current. With process technology improvements, the output stage can now be replaced with bipolar CMOS/DMOS technology, which combines the high component density and low power consumption of CMOS with the high current drive and speed of bipolar process. According to Avago, the switching speed is also now twice as fast as the previous generation, reducing the dead time when both the high-side and low-side transistors are off from 700 ns to 200 ns for improved system efficiency.
The ACPL-P343/W343, ACPL-P341/W341 and ACPL-P340/W340 optocouplers come in 4A, 3A and 1A maximum peak output current, respectively. They provide high-voltage insulation and protection for industrial drives, inverter and power supply applications.
Available in a stretched SO6 package that is 40 to 50 percent smaller than the Dual-inline (DIP) package the Avago ACPL-P34x and ACPL-W34x optocoupler family is priced starting at $1.30 each in 10,000 piece quantities.
