General Description:
TC4421/TC4422 are high-current buffers/drivers
capable of driving large MOSFETs and IGBTs.
These devices are essentially immune to any form of
upset, except direct overvoltage or over-dissipation.
They cannot be latched under any conditions within
their power and voltage ratings. These parts are not
subject to damage or improper operation when up to
5V of ground bounce is present on their ground
terminals. They can accept, without damage or logic
upset, more than 1A inductive current of either polarity
being forced back into their outputs. In addition, all
terminals are fully protected against up to 4 kV of
electrostatic discharge.
The TC4421/TC4422 inputs may be driven directly
from either TTL or CMOS (3V to 18V). 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.
With both surface-mount and pin-through-hole
packages and four operating temperature range
offerings, the TC4421/TC4422 family of 9A MOSFET
drivers fits into any application where high gate/line
capacitance drive is required.
