Integrated circuits are a critical component of modern electronics, and gate drivers are one of the most important types of integrated circuits that exist. The TC4426AEMF713 is a gate driver widely used in a variety of electronic applications. This article will explain the application field and working principle of the TC4426AEMF713 to provide a better understanding of how this important component works.

The TC4426AEMF713 is a high and low side gate driver that operates over a wide voltage range of up to 40 volts. It is capable of driving both N-channel and P-channel MOSFETs (Metal Oxide Semiconductor Field-Effect Transistor) and bipolar junction transistors (BJT). This makes the TC4426AEMF713 highly versatile and suitable for use in a variety of electronic devices. This gate driver can be used in power converters such as flyback, buck, and boost converters where it is used to drive the power switches. It can also be used in motor drives, AC and DC drives, relays, and other devices which require fast switching and high power. Additionally, the TC4426AEMF713 can be used in lighting devices such as light-emitting diodes (LEDs) and laser diodes to control the current and voltage for proper operation.

The TC4426AEMF713 is a low on-resistance, high-voltage driver, produced by Toshiba. The key feature of the TC4426AEMF713 is its low voltage supplying ability. The circuit requires a power supply of only 1.5-5 V to operate, which is much lower than many other gate drivers. This obviously makes the TC4426AEMF713 an attractive solution when designing systems which require a low-voltage power source. Additionally, the TC4426AEMF713 has a built-in thermal protection system to protect the driver from being damaged by excessive temperatures.

The internal working principle of the TC4426AEMF713 is quite straightforward. It operates on the principle of a H-bridge, which is a quadrant of transistors configured in such a way that it can control current flow in both directions. The TC4426AEMF713 is configured with four switches, two in each direction. The two switches in one direction are used to control the current flow, while the other two switches are used to protect the circuitry from static voltage. The four switches are then connected to the gate driver control logic, which is responsible for controlling the on/off state of the switches.

The TC4426AEMF713 provides a high level of protection for the connected MOSFETs and BJTs. It has built-in over voltage protection and current fold back which limits the amount of current that can be driven through the connected devices. It also has a short circuit protection which will turn off the driver when a short circuit is detected. Additionally, it has built-in Adaptive Shoot-Through Prevention (ASTP) technology which prevents the potential damage caused by shoot-through currents.

The TC4426AEMF713 is a highly versatile gate driver that is suitable for use in a wide range of applications. Its wide voltage range and low-voltage operation make it an attractive solution for systems which require a small power source. Additionally, its built-in protection features make it well suited for devices which require high levels of protection. Overall, the TC4426AEMF713 is a reliable and efficient gate driver that is suitable for a wide range of applications.
