TC4431/TC4432
1.5A High-Speed 30V MOSFET Drivers
Features
General Description
• High Peak Output Current – 1.5 A
• Wide Input Supply Operating Range:
- 4.5V to 30V
The TC4431/TC4432 are 30V CMOS buffer/drivers
suitable for use in high-side driver applications. They
will not latch up under any conditions within their power
and voltage ratings. They can accept, without damage
or logic upset, up to 300 mA of reverse current (of
either polarity) being forced back into their outputs. All
terminals are fully protected against up to 4 kV of
electrostatic discharge.
• High Capacitive Load Drive Capability:
- 1000 pF in 25 nsec
• Short Delay Times – <78 nsec Typ.
• Low Supply Current:
- With Logic ‘1’ Input – 2.5 mA
- With Logic ‘0’ Input – 300 µA
• Low Output Impedance – 7 Ω
• Latch-Up Protected: Will Withstand >300 mA
Reverse Current
Under-voltage lockout circuitry forces the output to a
‘low’ state when the input supply voltage drops below
7V. For operation at lower voltages, disable the lockout
and start-up circuit by grounding pin 3 (LOCK DIS); for
all other situations, pin 3 (LOCK DIS) should be left
floating. The under-voltage lockout and start-up circuit
gives brown out protection when driving MOSFETS.
• ESD Protected – 4 kV

Supply Input (VDD
)
3.4
Ground (GND)
The VDD input is the bias supply input for the MOSFET
driver and is rated for 4.5V to 30V with respect to the
ground pins. The VDD input should be bypassed to
ground with a local ceramic capacitor. The value of this
capacitor should be chosen based on the capacitive
load that is being driven.
The ground pins are the return path for the bias current
and for the high peak currents which discharge the load
capacitor. Both ground pins should be used to ensure
proper operation. The ground pins should be tied into a
ground plane or have short traces to the bias supply
source return.
3.2
Control Input (IN)
3.5
Drive Output (OUT)
The MOSFET driver input is a TTL/CMOS compatible
input with 250 mV of hysteresis between the high and
low threshold voltages. If an input signal level of greater
than 12V is applied to the device, a series current
limiting resistor is recommended.
The TC4431/TC4432 devices have individual source
and sink output pins. This feature can be used to adjust
the rise and fall time independently by adding separate
charge and discharge resistors external to the device.
Pin 7 (source output) can source 3 A peak currents into
capacitive loads and pin 6 (sink output) can sink 1.5 A
peak currents from a capacitive load.
3.3
Lockout Disable (LOCK DIS)
The lockout pin enables/disables the undervoltage
lockout feature of the device. If undervoltage lockout is
desired (output is not enabled until the bias voltage
reaches 8.4V (typical) on the rising edge and is
disabled when the bias voltage reaches 7.7V (typical)
on the falling edge), the lockout pin should be left float-
ing. If operation below 7V is desired, the lockout pin
should be tied to ground.

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