The TC4426VUA is an IC (integrated circuit) component that belongs to the gate drivers family. It is a high-speed MOSFET driver designed to drive high-current MOSFETs in various applications, including motor controllers, power management systems, and switching power supplies.
Some key features of the TC4426VUA include:
1. High output current capability: The TC4426VUA can source and sink a peak output current of up to 1.5A, facilitating the efficient and reliable operation of MOSFETs with relatively high gate capacitances.
2. Wide input voltage range: It accepts input voltages ranging from 4.5V to 18V, making it compatible with a wide range of power supply systems.
3. Short propagation delay: The propagation delay of the TC4426VUA is typically around 55ns, ensuring fast and precise switching of MOSFETs, thus minimizing power losses and enhancing circuit performance.
4. Low output impedance: With a low output impedance of about 6 ohms, the TC4426VUA can rapidly charge and discharge MOSFET gates, further improving switching efficiency.
5. Under-voltage lockout (UVLO) protection: It integrates a UVLO circuit that prevents the driver from operating when the input voltage falls below a specified threshold value, safeguarding the MOSFET and the entire circuit against potential damage
