Application Field of TC4423EOE Gate Driver

TC4423EOE gate drivers are mainly used in applications with high current requirements and where the current sharing is required. It also supports fault protection feature and can be used in automotive applications. Some of the applications which can make use of the TC4423EOE gate drivers are as follows:

• Switched-mode power supplies
• DC-DC converters
• Motor and solenoid circuits
• High-speed switching circuits

The product has the necessary protection circuitry for over-voltage, over-current, and over-temperature protection. This makes the product suitable for automotive applications as well, like in fuel pumps and ignition modules. The high isolation voltage makes it a perfect choice for high voltage motor control circuits.

Working Principle of TC4423EOE Gate Driver

The TC4423EOE gate driver consists of an integrated-circuit (IC) and a power MOSFET. The IC consists of 4 pins in total, two of which are source and sink terminal pins, and the other two pins are control pins. The source pin provides the source current to the power MOSFET gate, and the sink pin is used to discharge the current.

The working of the IC is controlled by the input of the control pins. When the voltage at the control pins is below 2V, it switches the power MOSFET gate current into the “OFF” state. When the voltage is between 2V and 7V, it switches the power MOSFET gate current into the “ON” state. When the voltage is above 7V, the power MOSFET gate current is in the “OFF” state.

The power MOSFET gate is used to switch the current in the gate driver circuit. The current which is switched by the power MOSFET gate is sent to the controlling device or the motor. The circuit also has a protection circuitry which provides the necessary protection, over-voltage, over-current, and over-temperature protection. The protection circuitry makes the product suitable for automotive applications.

Conclusion

TC4423EOE gate driver is a very special product in the gate driver series. It integrates a power MOSFET gate driver and a protection circuitry into one single package and is mainly used in high current applications. The working of the product is controlled by the input at the control pins. The product is suitable for applications like switched-mode power supplies, DC-DC converters, and motor and solenoid circuits.
