MICROCHIP TC4424AVOA713 is a low-side gate driver designed for use in circuit boards that require moderate-to-high power consumption. In this article, you are going to find out what a gate driver means and how you can maximize the properties of the MICROCHIP TC4424AVOA713.
What Does a Gate Driver Mean in Circuits?
According to Wikipedia, a gate driver is a “power amplifier that accepts a low-power input from a Controller IC and produces a high-current drive input for the gate of a high-power transistor.”
What this means is that you can use a gate driver to “drive current” from a lower-powered input source. By converting the low current, you would be able to derive a higher output to be used in the high-power device, such as a power MOSFET or IGBT.
Why the MICROCHIP TC4424AVOA713 is Needed for High-Power Transmissions
By default, a gate driver is only used when there is low-power from the input device. As a low-side gate driver, MICROCHIP TC4424AVOA713 plays a critical role to make that work.
Since a high voltage is needed to access the gate of a high-power transistor, such as a MOSFET or IGBT, the MICROCHIP TC4424AVOA713 ought to be used.
That way, the low-input power will be converted to high-current drive that would be used to gain access to the gate and emitter/source terminal of the MOSFET or IGBT.

What You Need to Know About MICROCHIP TC4424AVOA71’s Low-Side Configuration
MICROCHIP TC4424AVOA71 uses a low-side configuration and we want to talk about it.
A low-side gate driver is commonly used for devices that require more power. These include heaters and motors.
According to Texas Instruments, a low-side gate driver is designed to bolster the performance of the circuit board by reducing switching-related losses, improving the device’s system density and improving the system or device’s resilience to noise.
How the Non-Inverting Input Works in MICROCHIP TC4424AVOA71
How does the non-inverting input type used in the MICROCHIP TC4424AVOA71 work? According to Stack Exchange, the non-inverting gate driver works by giving a corresponding value to the input. For example, if a higher logic is connected to the input, the output will be higher.
This is much better than an inverting gate driver that does the opposite. If you were using this, the connection of a logic high would give a lower output, while a low logic input sets the output high.
Conclusion
MICROCHIP TC4424AVOA71 uses 2 drivers, 2 inputs and a Surface Mount Technology (SMT) design to facilitate the conversion of low-power input to high-powered operations.
