General Description
The TC4451/TC4452 are single-output MOSFET
drivers. These devices are high-current buffer/drivers
capable of driving large MOSFETs and Insulated Gate
Bipolar Transistors (IGBTs). The TC4451/TC4452 have
matched output rise and fall times, as well as matched
leading and falling-edge propagation delay times. The
TC4451/TC4452 devices also have very low cross-
conduction current, reducing the overall power
dissipation of the device.
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 1.5A 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 TC4451/TC4452 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
packages, in addition to a wide operating temperature
range, the TC4451/TC4452 family of 12A MOSFET
drivers fit into most any application where high gate/line
capacitance drive is required.
