NCP5392PMNR2G

The NCP5392PMNR2G is ON Semiconductor’s dual protected load-switch IC. It provides two independent power channels that can safely switch supply rails in portable, automotive, and embedded systems. Each channel includes high-side switching with protection features such as current limiting, undervoltage lockout, overcurrent protection, thermal shutdown, and reverse polarity protection. The device supports separate enable controls and fault/diagnostic outputs for simple health monitoring and interlocks. The compact 8-pin MNR2G package suits space-constrained designs. Typical applications include powering MCUs, sensors, or peripheral devices from a main supply or battery with built-in fault protection. For exact electrical specifications, pinout, and application notes, consult the ON Semiconductor datasheet for the NCP5392PMNR2G.
