MICROCHIP TC4405EOA

TC4404/TC4405
1.5A Dual Open-Drain MOSFET Drivers
Features:
General Description:
• Independently Programmable Rise and Fall
Times
• Low Output Impedance – 7Ω Typ.
• High Speed tR, tF – <30 nsec with 1000 pF Load
• Short Delay Times – <30 nsec
• Wide Operating Range:
- 4.5V to 18V
• Latch-Up Protected: Will Withstand > 500 mA
Reverse Current (Either Polarity)
• Input Withstands Negative Swings Up to -5V
The TC4404/TC4405 are CMOS buffer-drivers
constructed with complementary MOS outputs, where
the drains of the totem-pole output have been left
separated so that individual connections can be made
to the pull-up and pull-down sections of the output. This
allows the insertion of drain-current-limiting resistors in
the pull-up and/or pull-down sections, allowing the user
to define the rates of rise and fall for a capacitive load;
or a reduced output swing, if driving a resistive load, or
to limit base current, when driving a bipolar transistor.
Minimum rise and fall times, with no resistors, will be
less than 30 nsec for a 1000 pF load.
Applications:
For driving MOSFETs in motor-control applications,
where slow-ON/fast-OFF operation is desired, these
devices are superior to the previously used technique
of adding a diode-resistor combination between the
driver output and the MOSFET, because they allow
accurate control of turn-ON, while maintaining fast turnOFF and maximum noise immunity for an OFF device.

When used to drive bipolar transistors, these drivers
maintain the high speeds common to other Microchip
drivers. They allow insertion of a base current-limiting
resistor, while providing a separate half-output for fast
turn-OFF. By proper positioning of the resistor, either
npn or pnp transistors can be driven.
For driving many loads in low-power regimes, these
drivers, because they eliminate shoot-through currents
in the output stage, require significantly less power at
higher frequencies, and can be helpful in meeting
low-power budgets.

TC4404/TC4405
Because neither drain in an output is dependent on the
other, these devices can also be used as open-drain
buffer/drivers where both drains are available in one
device, thus minimizing chip count. Unused open
drains should be returned to the supply rail that their
device sources are connected to (pull-downs to
ground, pull-ups to VDD), to prevent static damage. In
addition, in situations where timing resistors or other
means of limiting crossover currents are used, like
drains may be paralleled for greater current carrying
capacity.
These devices are built to operate in the most demanding electrical environments. They will not latch-up
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 their ground
pin; and they can accept, without damage or logic
upset, up to 1/2 amp of reverse current (of either
polarity) being forced back into their outputs. All
terminals are fully protected against up to 2 kV of
electrostatic discharge.

APPLICATIONS INFORMATION

Circuit Layout Guidelines
In addition, it is advisable that low ESR bypass capacitors (4.7 μF or 10 μF tantalum) be placed as close to
the driver as possible. The driver should be physically
located as close to the device it is driving as possible to
minimize the length of the output trace.
Avoid long power supply and ground traces (added
inductance causes unwanted voltage transients). Use
power and ground planes wherever possible.

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.
