NCT3521U-2

The NCT3521U-2 is an integrated 80mΩ power switch IC designed for high-side load switching applications. The NCT3521U-2 operates with an input voltage range from 3V to 5.5V, making it ideal for both 3V and 5V systems. The NCT3521U-2 also features an under-voltage lock out which turns the switch off when an input under-voltage condition exists. The NCT3521U-2 has additional protection including current limiting and thermal shutdown to prevent catastrophic switch failure caused by increasing power dissipation when continuous heavy load or short circuit occurs. The NCT3521U-2 features a shutdown discharge function and a soft-start function. Its low quiescent current and small package makes it suitable for battery-powered equipment. In shutdown mode, the quiescent current is less than 1uA.
