With today\'s rising demand for smart devices and operation efficiency, the use of modern PMIC (Power Management Integrated Circuit) technologies have become increasingly prevalent. In particular, the utilization of advanced Gate Drivers have helped bring forth immense improvements in both the speed and accuracy with which power devices are operated. A unique example of this is the TC4468EPD Gate Driver, which has the features and capabilities required to help make such devices more energy efficient and reliable.In this article, we will provide a detailed overview of the TC4468EPD Application Field and Working Principle, in order to better understand its use and benefits.The TC4468EPD is a high voltage, low-side gate driver designed specifically to drive high-side and low-side N-channel power MOSFETs. It is capable of operating both in 4V to 80V display applications and in 24V to 80V industrial applications. The device features an adjustable level-shift between the low-side and high-side gate drive outputs, enabling it to provide the required gate swing for both the high-side and low-side FETs. The TC4468EPD is also able to provide adjustable over-voltage protection.The TC4468EPD works by using an internal biasing control block, which facilitates the provision of the required gate drive output level for the low-side and high-side FETs. One of the most unique features of the IC is that it features a "bridge-keeper" feature,which limits the amount of gate charge that can be stored in the gate-drive channels, thus minimizing the risk of static losses and preventing damage to the power FETs.In addition to the bridge keeper feature, the TC4468EPD also features a short-on-time delay circuit, which helps prevent the current spikes that can occur due to switching delays. This reduces the need for tall gate drivers, which are otherwise needed in similar applications. The TC4468EPD can also be used in isolated power supply applications, as the drivers feature short-on-time delay circuitry to ensure that the power FETs are protected from unexpected current spikes caused by switching delays. This allows for higher power efficiency and improved reliability in such applications.Finally, the TC4468EPD also features adjustable dead-time delay, which helps reduce the severity of shoot-through current that may occur during switching operations. This eliminates the need for complex, external components for shoot-through protection and thereby reduces the cost of the system.In conclusion, the TC4468EPD is an ideal Gate Driver for those looking to build efficient and reliable power-control systems, offering both adjustable level-shift, adjustable over-voltage protection, bridge-keeper and short-on-time delay circuitry, along with adjustable dead-time delay. All of these features combine to make the TC4468EPD a cost effective and reliable solution for today\'s advanced power-control systems.
