3段高压驱动电源芯片--PN7336

一　概述

The PN7336 is a high voltage, high speed power MOSFET and IGBT drivers with a three independent high and low side
referenced output channels for 3-phase applications. The floating channels can be used to drive N-channel power MOSFETs
or IGBTs in the high side configuration which operates up to 600V. Logic inputs are compatible with CMOS or LSTTL outputs,down to 3.3V logic. A current trip function which terminates all six outputs can be derived from an external current sense　resistor. An enable function is available to terminate all six outputs simultaneously. An open-drain FAULT signal is provided　to indicate that an over-current or under-voltage shutdown has occurred. Over-current fault conditions are cleared automatically after a delay programmed externally via an RC network connected to the RCIN input. 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.
