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 both surface-mount and pin-through-hole

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.
