Applications
•
•
•
•
A 2500 pF capacitive load will be driven to 18V in
25 nsec. The rapid switching times with large
capacitive loads minimize MOSFET switching power
losses.
A TTL/CMOS input logic level is translated into an
output voltage swing that equals the supply voltage and
will swing to within 25 mV of ground or VDD. Input voltage swing may equal the supply voltage. Logic input
current is under 10 µA, making direct interface to
CMOS/bipolar switch-mode power supply controllers
easy. Input “speed-up” capacitors are not required.
The CMOS design minimizes quiescent power supply
current. With a logic ‘1’ input, power supply current is
5 mA maximum and decreases to 0.5 mA for logic ‘0’
inputs.

VDD
Supply input, 7V to 18V
Supply Input (VDD)
The VDD input is the bias supply for the MOSFET driver
and is rated for 7.0V 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 value of 1.0 µF is suggested.
3.2
Control Input (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
(OUTPUT)
The MOSFET driver output is a low-impedance, CMOS
push-pull style output, capable of driving a capacitive
load with 6.0A peak currents.
3.4
Ground (GND)
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.

APPLICATIONS INFORMATION
4.1
Supply Bypassing
VDD = 18V
Charging and discharging large capacitive loads
quickly requires large currents. For example, charging
a 2500 pF load to 18V in 25 nsec requires a 1.8A
current from the device's power supply.
4.2
Grounding
The high-current capability of the TC429 demands
careful PC board layout for best performance. Since
the TC429 is an inverting driver, any ground lead
impedance will appear as negative feedback that can
degrade switching speed. The feedback is especially
noticeable with slow rise-time inputs, such as those
produced by an open-collector output with resistor pullup. The TC429 input structure includes about 300 mV
of hysteresis to ensure clean transitions and freedom
from oscillation, but attention to layout is still
recommended.
Figure 4-3 shows the feedback effect in detail. As the
TC429 input begins to go positive, the output goes
negative and several amperes of current flow in the
ground lead. A PC trace resistance of as little as 0.05
can produce hundreds of millivolts at the TC429 ground
pins. If the driving logic is referenced to power ground,
the effective logic input level is reduced and oscillations
may result.

VOLTAGE (5V/DIV)
To ensure optimum device performance, separate
ground traces should be provided for the logic and
power connections. Connecting logic ground directly to
the TC429 GND pins ensures full logic drive to the input
and fast output switching. Both GND pins should be
connected to power ground.
1, 8
VOLTAGE (5V/DIV)
To ensure low supply impedance over a wide frequency
range, a parallel capacitor combination is recommended for supply bypassing. Low-inductance ceramic
disk capacitors with short lead lengths (< 0.5 in.) should
be used. A 1 µF film capacitor in parallel with one or two
0.1 µF ceramic disk capacitors normally provides
adequate bypassing.

Input Stage
The input voltage level changes the no-load or
quiescent supply current. The N-channel MOSFET
input stage transistor drives a 3 mA current source
load. With a logic ‘1’ input, the maximum quiescent
supply current is 5 mA. Logic ‘0’ input level signals
reduce quiescent current to 500 µA maximum.
The TC429 input is designed to provide 300 mV of
hysteresis, providing clean transitions and minimizing
output stage current spiking when changing states.
Input voltage levels are approximately 1.5V, making the
device TTL-compatible over the 7V to 18V operating
supply range. Input pin current draw is less than 10 µA
over this range.
The TC429 can be directly driven by TL494, SG1526/
1527, SG1524, SE5560 or similar switch-mode
power supply integrated circuits. By off-loading the
power-driving duties to the TC429, the power supply
controller can operate at lower dissipation, improving
performance and reliability.
Peak Output Current Test
Power Dissipation
CMOS circuits usually permit the user to ignore power
dissipation. Logic families such as the 4000 and 74C
have outputs that can only supply a few milliamperes of
current, and even shorting outputs to ground will not
force enough current to destroy the device. The TC429,
however, can source or sink several amperes and drive
large capacitive loads at high frequency. Since the
package power dissipation limit can easily be
exceeded, some attention should be given to power
dissipation when driving low-impedance loads and/or
operating at high frequency.
The supply current versus frequency and supply
current versus capacitive load characteristic curves will
aid in determining power dissipation calculations.
Table 4-1 lists the maximum operating frequency for
several power supply voltages when driving a 2500 pF
load. More accurate power dissipation figures can be
obtained by summing the three components that make
up the total device power dissipation.
Input signal duty cycle, power supply voltage and
capacitive load influence package power dissipation.
Given power dissipation and package thermal resistance, the maximum ambient operation temperature
is easily calculated. The 8-pin CERDIP junction-toambient thermal resistance is 150C/W. At +25C, the
package is rated at 800 mW maximum dissipation.
Maximum allowable junction temperature is +150C.
Three components make up total package power
dissipation:
• Capacitive load dissipation (PC)
• Quiescent power (PQ)
• Transition power (PT)
The capacitive load-caused dissipation is a direct
function of frequency, capacitive load and supply
voltage.

POWER-ON OSCILLATION
It is extremely important that all MOSFET
driver applications be evaluated for the
possibility of having high-power oscillations
occur during the power-on cycle.
Power-on oscillations are due to trace size, layout and
component placement. A ‘quick fix’ for most applications that exhibit power-on oscillation problems is to
place approximately 10 k in series with the input of
the MOSFET driver.

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
and may be superseded by updates. It is your responsibility to
ensure that your application meets with your specifications.
