高低侧栅驱动芯片--PN7008

一　概述

The PN7008 is a high voltage, high speed power MOSFET and IGBT driver. The floating channel driver can be used to drive two N-channel power MOSFET or IGBT independently which operates up to 600 V. Logic inputs are compatible with standard CMOS or LSTTL output, down to 3.3V logic. The output drivers feature a high pulse current buffer stage designed for minimum driver cross conduction. Propagation delays are matched to simplify use in high frequency applications. It has two versions PN7008A&PN7008B.
