The NIS5420MT5TXG is an Electronic Fuse Regulator manufactured by ON Semiconductor and it comes in a 10-WDFN (3x3) package. It offers a wide variety of protection features, including overvoltage protection, overcurrent protection, open-circuit protection, short-circuit protection, and reverse-battery protection. This part is designed for automotive applications, such as motor control, battery management, and charger control. The NIS5420MT5TXG is capable of operating within a wide input voltage range from 6V to 40V and can provide up to 5W of power. Additionally, it can regulate the output voltage to 3.3V, 5V, and adjustable voltage from 12V to 40V based on an external resistor. It includes a slew rate control for a soft start which helps to reduce the in-rush current. The device is suitable for highly integrated power management applications.
