MOSFET Drivers
• Space-Saving, Thermally-Enhanced, 8-Pin DFN
Package
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 crossconduction current, reducing the overall power
dissipation of the device.
Applications
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.

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.

3.1
Symbol
Supply Input (VDD)
The VDD input is the bias supply for the MOSFET driver
and is rated for 4.5V to 18V with respect to the ground
pin. The VDD input should be bypassed to ground with
a local ceramic capacitor. The value of the capacitor
should be chosen based on the capacitive load that is
being driven. A minimum value of 1.0 μF is suggested.
3.2
Control Input
The MOSFET driver input is a high-impedance,
TTL/CMOS-compatible input. The input also has
300 mV of hysteresis between the high and low
thresholds that prevents output glitching even when the
rise and fall time of the input signal is very slow.
3.3
CMOS Push-Pull Output
The MOSFET driver output is a low-impedance,
CMOS, push-pull style output capable of driving a
capacitive load with 12A peak currents. The MOSFET
driver output is capable of withstanding 1.5A peak
reverse currents of either polarity.

3.4
Ground
The ground pins are the return path for the bias current
and for the high peak currents that discharge the load
capacitor. The ground pins should be tied into a ground
plane or have very short traces to the bias supply
source return.
3.5
Exposed Metal Pad
The exposed metal pad of the 6x5 DFN package is not
internally connected to any potential. Therefore, this
pad can be connected to a ground plane or other
copper plane on a Printed Circuit Board (PCB) to aid in
heat removal from the package.
3.6
Metal Tab
The metal tab of the TO-220 package is connected to
the VDD potential of the device. This connection to VDD
can be used as a current carrying path for the device.

Pb-free JEDEC designator for Matte Tin (Sn)
This package is Pb-free. The Pb-free JEDEC designator ( e3 )
can be found on the outer packaging for this package.
In the event the full Microchip part number cannot be marked on one line, it will
be carried over to the next line, thus limiting the number of available
characters for customer-specific information.

Note the following details of the code protection feature on Microchip devices:
•
Microchip products meet the specification contained in their particular Microchip Data Sheet.
•
Microchip believes that its family of products is one of the most secure families of its kind on the market today, when used in the
intended manner and under normal conditions.
•
There are dishonest and possibly illegal methods used to breach the code protection feature. All of these methods, to our
knowledge, require using the Microchip products in a manner outside the operating specifications contained in Microchip’s Data
Sheets. Most likely, the person doing so is engaged in theft of intellectual property.
•
Microchip is willing to work with the customer who is concerned about the integrity of their code.
•
Neither Microchip nor any other semiconductor manufacturer can guarantee the security of their code. Code protection does not
mean that we are guaranteeing the product as “unbreakable.”
Code protection is constantly evolving. We at Microchip are committed to continuously improving the code protection features of our
products. Attempts to break Microchip’s code protection feature may be a violation of the Digital Millennium Copyright Act. If such acts
allow unauthorized access to your software or other copyrighted work, you may have a right to sue for relief under that Act.

applications and the like is provided only for your convenience
