TC4426AM/TC4427AM/TC4428AM Data Sheet

TC4426AM/TC4427AM/TC4428AM
1.5A Dual High-Speed Power MOSFET Drivers
Features
General Description
• High Peak Output Current: 1.5A
• Wide Input Supply Voltage Operating Range:
- 4.5V to 18V
• 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:
- With Logic ‘1’ Input – 1 mA (typ.)
- With Logic ‘0’ Input – 100 µA (typ.)
• Low Output Impedance: 7(typ.)
• Latch-Up Protected: Will Withstand 0.5A Reverse
Current
• Input: Will Withstand Negative Inputs Up to 5V
• ESD Protected: 4 kV
• Pin-compatible with the
TC426M/TC427M/TC428M and
TC4426M/TC4427M/TC4428M
• Wide Operating Temperature Range:
- -55°C to +125°C
• See TC4426A/TC4427A/TC4428A Data Sheet
(DS21423) for additional temperature range and
packaging offerings
The TC4426AM/TC4427AM/TC4428AM are improved
versions of the earlier TC4426M/TC4427M/TC4428M
family of MOSFET drivers. In addition to matched rise
and fall times, the TC4426AM/TC4427AM/TC4428AM
devices have matched leading and falling edge
propagation delay times.
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.
The TC4426AM/TC4427AM/TC4428AM MOSFET
drivers can easily charge/discharge 1000 pF gate
capacitances in under 30 ns, while providing 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.

Outputs A & B (OUT A and OUT B)
MOSFET driver OUT A & B are low-impedance,
CMOS, push-pull style outputs. The pull-down and pullup devices are of equal strength, making the rise and

Supply input
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 with local
ceramic capacitors. The value of these capacitors
should be chosen based on the capacitive load that is
being driven.
Output A
No connection
Inputs A & B (IN A and IN B)
MOSFET driver IN A & B are high-impedance,
TTL/CMOS-compatible inputs. These inputs also have
300 mV of hysteresis between the high and low
thresholds, which prevents output glitching even when
the rise and fall time of the input signal is very slow.
3.2
Ground (GND)
The GND 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.

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.
Information contained in this publication regarding device
applications and the like is provided only for your convenience
