NIV3071 4-Channel eFuse Solution

onsemi NIV3071 is a versatile and robust electronic fuse (eFuse) designed to provide reliable current protection for a wide range of applications. Operating within an 8 V to 60 V range and capable of handling up to 10 A total current (2.5 A per channel), this 4-channel eFuse is housed in a compact 5 mm x 6 mm package. Each channel operates independently, offering protection against output shorts, overloads, and overcurrent events. The NIV3071 is particularly well-suited for automotive applications, including zonal control units, ADAS domain controllers, and telematics. Its flexibility allows it to manage multiple loads from different power supplies or combine outputs for higher current demands. The device features an internal soft-start delay, adjustable current limit settings, and a built-in thermal shutdown circuit with auto-retry capability, ensuring continuous operation even after fault conditions are cleared. With its high-side configuration and active-high enable pins, the NIV3071 provides precise control and reliable protection for critical downstream loads.
