WXNSIC NSG73933

The NSG73933 is a high-voltage, high-speed power MOSFET/IGBT high- and low-side driver series IC with isolated logic ground and power ground, effectively reducing power-stage noise interference on logic circuits. Dead time is flexibly configurable via external resistors. Integrated protection circuits include high- and low-side UVLO and overvoltage clamp circuits. The device features high-current pulse output capability, logic input levels compatible with CMOS or LSTTL logic outputs as low as 3.3V, a maximum output current of 4A, and a floating channel maximum operating voltage of 700V. Suitable for driving N-channel high-voltage power MOSFET/IGBT devices.
