            高壓供電驅動芯片--PN7008A/B

            產品分類: 電機驅動芯片
              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.
