The TC4404EOA is a high-speed, non-inverting power MOSFET gate driver. This device is designed as an advanced logic level driver solution for robust high-side and low-side switching applications. It offers a wide range of circuit protection features, to ensure reliable and safe operation.

The TC4404EOA is designed for the power stage operating conditions of high voltage and high current. It is suitable for MOSFET gate drive applications up to 4A of peak current, and can operate in a wide range of operating conditions from 0 volts to 24 volts. It integrates an active pull-down and an active pull-up output stage to reduce charging/discharging of spread parasitic gate capacitance. In addition, the TC4404EOA has several features that enable enhanced performance and efficient design for gate drive applications.

TC4404EOA is suitable for various PMIC - Gate Driver applications, including motor controls, power factor correction, and other power supplies. The device can drive high-side and low-side MOSFETs and IGBTs. It integrates functional features including supply voltage regulation and over voltage protection, under voltage protection, and shutdown input logic, making it an ideal choice for modern high-power designs.

The TC4404EOA uses a non-inverting output stage to reduce the output voltage rise time of the MOSFET. It uses active pull-up and pull-down elements to minimize residual charge, which reduces the need for external protection diodes. The device also features programmable slew rate limiting control and adjustable drive strength for low side and high side MOSFETs with various load conditions. The drive strength level can be adjusted to reduce ringing and improve EMI performance.

An integral pull-up resistor leverages the ultra-fast turn-off speed benefits of the high-voltage MOSFET chip, while the over-voltage protection circuit prevents any device failure due to over-voltages. The device also has an active shutdown pin that can pull the output low in the event of a fault, ensuring the protection of the MOSFET. The TC4404EOA also has an adjustable gate delay time, which can be adjusted to reduce the switching time of the MOSFET.

Furthermore, the TC4404EOA integrates several circuit protection features to protect against various fault conditions and improve the safety of the whole power system. This includes short circuit protection, current limiting and thermal shutdown. The device is also pin-to-pin compatible with the widely used TLP5600 and IR2530 gate drivers, allowing for easy replacement of existing gate drivers in end-user system.

The TC4404EOA is ideal for advanced applications such as gate driver protection, gate charge optimization, gate drive output current control and advanced power control. It is also suitable for applications ranging from LED lighting to motor control, switched-mode power supplies, and other power applications. It is designed to meet stringent requirements of modern high-performance systems and is RoHS compliant and UL certified.
