Reverse Current Input Will Withstand Negative Inputs up to 5V Pin-Compatible with the TC4420/TC4429
6A MOSFET Driver Space-saving 8-Pin 6x5 DFN-S Package 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 …
