TC4426A/TC4427A/TC4428A
1.5A Dual High-Speed Power MOSFET Drivers
General Description
Features
• High Peak Output Current – 1.5A
• Wide Input Supply Voltage Operating Range:
- 4.5V to 18V
The TC4426A/TC4427A/TC4428A are improved
versions of the earlier TC4426/TC4427/TC4428 family
of MOSFET drivers. In addition to matched rise and fall
times, the TC4426A/TC4427A/TC4428A devices have
matched leading and falling edge propagation delay
times.
• High Capacitive Load Drive Capability – 1000 pF
in 25 ns (typ.)
• Short Delay Times – 30 ns (typ.)
• Matched Rise, Fall and Delay Times
• Low Supply Current:
These devices are highly latch-up resistant under any
conditions within their power and voltage ratings. They
are not subject to damage when up to 5V of noise
spiking (of either polarity) occurs on the ground pin.
They can accept, without damage or logic upset, up to
500 mA of reverse current (of either polarity) being
forced back into their outputs. All terminals are fully
protected against Electrostatic Discharge (ESD) up to
4 kV.
- With Logic ‘1’ Input – 1 mA (typ.)
- With Logic ‘0’ Input – 100 µA (typ.)
• Low Output Impedance – 7Ω (typ.)
• Latch-Up Protected: Will Withstand 0.5A Reverse
Current
• Input Will Withstand Negative Inputs Up to 5V
• ESD Protected – 4 kV
The TC4426A/TC4427A/TC4428A MOSFET drivers
can
easily
charge/discharge
1000 pF
gate
• Pin-compatible with TC426/TC427/TC428 and
TC4426/TC4427/TC4428
capacitances in under 30 ns. These devices provide
low enough impedances in both the on and off states to
ensure the MOSFET's intended state will not be
affected, even by large transients.

3.1
Inputs A and B
3.4
Supply Input (V
)
DD
MOSFET driver inputs A and B are high-impedance,
TTL/CMOS compatible inputs. These inputs also have
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.
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 with local
ceramic capacitors. The value of these capacitors
should be chosen based on the capacitive load that is
being driven.
3.2
Ground (GND)
3.5
Exposed Metal Pad
The ground pin is the return path for both the bias
current and the high peak current that discharges the
external load capacitance. The ground pin should be
tied into a ground plane or have a very short trace to the
bias supply source return.
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, to aid in heat
removal from the package.
3.3
Output A and B
MOSFET driver outputs A and B are low-impedance,
CMOS push-pull style outputs. The pull-down and pull-
up devices are of equal strength, making the rise and
fall times equivalent.

NOTES:
DS21423E-page 16
2004 Microchip Technology Inc.
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.
