NEC Electronics - IGBT/MOSFET gate drive optocoupler with MOSFET-MOSFET output form

The new IGBT gate drivers are designed for 2.5A max. peak output current and will be released in two package versions: The PS9505 comes in a conventional 8-pin dual inline package (DIP) and the PS9305 is offered in a 8-pin shrunk dual inline package (S-DIP) with a pin to pin distance of 1.27mm, reducing the on board footprint to half of a conventional 8-pin DIP.



The PS9505 and PS9305 series consist of a GaAlAs LED at the input side and a photo diode with signal processing circuit and power stage at the output side. The isolated drivers feature the combination of a high speed optocoupler providing high isolation voltage as well as IGBT/MOSFET driving characteristics supplying high output voltage and current.
