TC4422AVOA Introduction

It is highly recommended that you give Microchip Technology’s TC4422AVOA power driver some thought if you are searching for a durable and dependable method to regulate your high-power transistors. This device’s lightning-fast response times, made possible by its maximum propagation delay of only 49 ns, make it ideally suited for high-performance applications where timing is paramount. In addition, this product comes packaged in a tube, adding an additional defense layer against potential damage during transport and storage.

As a result, you can rest easy knowing that none of the individual parts will be harmed. This gate driver is adaptable to various applications because of its extensive temperature range of -40 degrees Celsius to 125 degrees Celsius and large working voltage range of 4.5 to 18 volts. The TC4422AVOA is a high-performance and reliable power driver manufactured by Microchip Technology. If you need a power driver for your next project, purchasing one of these is highly recommended.

TC4422AVOA General Description

The TC4421A/TC4422A series of single-output MOSFET drivers is an upgraded version of the TC4421/TC4422 MOSFET driver family that came out previously. These devices are high-current buffers/drivers capable of driving big MOSFETs and Insulated Gate Bipolar Transistors (IGBTs). The TC4421A and TC4422A have output rise and fall times that are matched to one another, as well as leading-edge and falling-edge propagation delay periods that are matched to one another. Moreover, the TC4421A/TC4422A devices have a very low cross-conduction current, which helps reduce the amount of power lost from the device. These devices are practically impervious to any sort of disturbance, with the exception of direct overvoltage or excessive dissipation.

They cannot have their latches engaged under any circumstances that fall within the parameters of their power and voltage ratings. When there is a ground bounce of up to 5 volts on the ground terminals of these components, there is no risk of damage or improper operation being caused by those components. They can tolerate an inductive current of greater than 1 A and either polarity being driven back into their outputs without suffering harm or causing their logic to become unstable. Also, any electrostatic discharge of up to 4 kV will not affect any terminals because they are all fully shielded. The TC4421A/TC4422A inputs can be driven directly from CMOS or TTL, depending on the application (3V to 18V). The input also has 300 millivolts worth of hysteresis built into it, which offers noise immunity and makes it possible for the device to be driven by waveforms with gradually rising or declining amplitude. The TC4422A family of 9A MOSFET drivers can be used in virtually any application. A high gate/line capacitance drive is required because they are available in surface-mount and pin-through-hole packaging and have a broad temperature range in which they operate.

TC4422AVOA Features

  • 10A is a high peak output current (typ.).
  • Low Cross-Conduction/Shoot-Through Current in the Output Stage.
  • 42 ns for matched short propagation delays (typ.).

TC4422AVOA Applications

  • Driving the Largest MOSFETs and IGBTs.
  • Local Power ON/OFF Switch.
  • Motor and Solenoid Driver.
  • LF Initiator.


● Supply Input (VDD)

The bias supply for the MOSFET driver is called the VDD input, and it may accept voltages ranging from 4.5V all the way up to 18V. (with respect to ground). Using a nearby ceramic capacitor, you should create a bypass that connects the VDD input to the ground. While determining the value of a capacitor, it is imperative to consider the capacitance of the load. A temperature of 1.0 degrees Fahrenheit is considered the absolute lowest temperature that may be tolerated.

● Control Input

The MOSFET driver input is characterized by high impedance and compatibility with CMOS and TTL. Even if the rise and fall rates of the input signal are relatively slow, the input signal has a hysteresis of 300 millivolts (mV) between the high and low thresholds, which prevents glitching of the output. This hysteresis allows for smooth transitions between the high and low thresholds.

● CMOS Push-Pull Output

The output of the MOSFET driver is a low-impedance CMOS output in the form of a push-pull switch capable of driving a capacitive load at peak currents of 9.0A. At its output, the MOSFET driver can sustain peak reverse currents of either polarity totaling 1.5A.

● Ground

The bias current and the high peak currents that drain the load capacitor follow a path that returns through the ground pins. This path is the return path. The ground pins should be connected to a ground plane, or the traces leading to the bias supply source return should be very short.

● Exposed Metal Pad

The exposed metal pad on the 6×5 DFN package is not connected to any voltage inside the component. Consequently, this pad can be attached to a ground plane or another copper plane on a printed circuit board (PCB), which will assist in removing heat from the package.

● Metal Tab

The metal tab of the TO-220 package is connected to the device’s VDD potential. This is done so for safety reasons. This connection to VDD can function as the device’s current carrying path because it is directly connected to VDD.


To summarize, the TC4422AVOA power driver that Microchip Technology offers is a solution that is both dependable and effective when it comes to regulating high-power transistors. This device is an excellent option for a wide range of applications because of its quick propagation delay time of only 49 ns and its tube packaging, which provides additional safety.
