TC4423COE is a gate driver integrated circuit used by power systems. It belongs to the family of PMIC - Gate Drivers and is characterized by its ability to drive high current and high voltage load. The TC4423COE is well suited to the automotive, industrial, and medical markets. It is ideal for controlling the gate of power MOSFETs, IGBTs, thyristors and SCRs.

The TC4423COE is a dual MOSFET driver with an active high and low side output, providing a high driving voltage of 15-20V, and a low driving voltage of 0.1V. It is designed for switching applications up to 1A @ 100V. The TC4423COE is resilient to high-dV/dt transients, is able to withstand short-circuit conditions and short turn-on delays when connected to the gate of the power MOSFETs. Its low RON leads to minimization of heat losses and is capable of driving LEDs and other inductive loads.

The TC4423COE is highly versatile and can be used in many different applications. It is used in power supplies systems, motor and generator controls, machine tools, solar inverters and other industrial equipment. It is also used in automotive electronic systems such as injection systems, electronic brakes, gear changes and lighting. In addition, it is used in medical equipment, digital monoblocks, electronic door locks and numerous other applications.

The TC4423COE has the following main features:

• Bi-directional MOSFET driver with active high and low side output.
• Synchronous rectifier output.
• Built in gate discharge, providing di/dt control.
• High output voltage, up to 20V.
• Low output voltage of 0.1V.
• High peak current drive.
• High switching frequency operation.
• Internal reverse battery protection.
• Capable of driving LEDs and inductive loads.

The TC4423COE works by providing the necessary voltage to the gate of the power Switch. By passing a voltage from the low side of the IC to the high side, the MOSFET is switched on. Then, a small current is discharged from the MOSFET until it is switched off. This is done in order to reduce the supply voltage below the level at which the switch is off.

When the switching frequency is increased and the loads become more inductive, the TC4423COE can regulate the current by sensing the voltage drop across the load and adjusting the output voltage accordingly. This is done to prevent any over-voltage, which would result in damaging the load. The TC4423COE also has the ability to reduce the driving voltage if the current is too high, thus preventing any over-heating.

In conclusion, the TC4423COE is a highly versatile gate driver that offers excellent performance in many applications. It is well suited for driving MOSFETs, IGBTs, thyristors and SCRs with high current and high voltage load applications. It provides high speed operation, protection from short-circuiting and reverse battery protection, and is capable of driving LEDs and other inductive loads. With its many features, it is an ideal solution for a wide range of applications.
