The LM5113SD/NOPB is a state-of-the-art gate driver designed and manufactured by Texas Instruments, tailored to meet the demanding requirements of modern power electronics. This sophisticated component is specifically engineered to drive gallium nitride (GaN) and enhancement-mode silicon carbide (SiC) power transistors, which are widely used in high-efficiency and high-density power conversion applications.

Key Features

• High-Speed Operation: The LM5113SD/NOPB offers fast propagation delays and rapid switching characteristics, which are essential for minimizing losses and improving the performance of power conversion systems.
• Dual Outputs: It comes with independent sink and source outputs that provide flexibility and enable optimal control of the power transistor's switching characteristics.
• High Drive Strength: The device can deliver peak source and sink currents of 1.2A and 5A, respectively, ensuring robust drive capability for a wide range of power transistors.
• Wide Supply Voltage Range: It operates over a wide supply voltage range from 5V to 14V, accommodating various system design requirements.
• Under-Voltage Lockout (UVLO): The built-in UVLO feature protects the power transistor by ensuring that the gate driver is operational only when the supply voltage is sufficient.
• Thermal Shutdown: An integrated thermal shutdown mechanism enhances reliability by preventing the device from operating at excessively high temperatures.

Applications

The LM5113SD/NOPB is suitable for a broad spectrum of applications, including:

• DC/DC power converters
