KTS1677A Load Switch Kinetic Technologies KTS1677A Load Switch provides enhanced system reliability and essential protection features. Kinetic KTS1677A Load Switch is a low-resistance MOSFET switch designed to be inserted between a power source and a load. This enables the device to isolate and protect against abnormal voltage and current conditions. The KTS1677A also includes protection features, such as input ±90V surge, input overvoltage, input under-voltage protection, reverse current blocking, over-current limiting, and overtemperature protection.
