NCP4421, NCP4422
9.0 A High-Speed MOSFET
Drivers
The NCP4421/4422 are high current buffer/drivers capable of
driving large MOSFETs and IGBTs.
They are essentially immune to any form of upset except direct
overvoltage or over鈥揹issipation 鈥?they cannot be latched under any
conditions within their power and voltage ratings; they are not subject
to damage or improper operation when up to 5.0 V of ground bounce is
present on their ground terminals; they can accept, without either
damage or logic upset, more than 1.0 A inductive current of either
polarity being forced back into their outputs. In addition, all terminals
are fully protected against up to 4.0 kV of electrostatic discharge.
The inputs may be driven directly from either TTL or CMOS (3.0 V
to 18 V). In addition, 300 mV of hysteresis is built into the input,
providing noise immunity and allowing the device to be driven from
slowly rising or falling waveforms.
