5. Application Information

The TPS26602PWPR is an industrial electronic fuse typically used in hot swap and power rail protection applications. It operates from 4.2 V to 60 V with programmable current limit, overvoltage, undervoltage and reverse polarity protection. The device helps control inrush currents and provides robust reverse current protection and records wiring errors in systems such as PLCs, industrial PCs, control and automation, and sensors. The device also provides robust protection against multiple faults on the system rail. The Detail Designer section can be used to select component values for the device. Alternatively, complete designs can be generated using WEBENCH® software.
