Kinetic Technologies 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.

The KTS1677A operates using a wide input voltage range of 3V to 30V, making it ideal for USB PD applications. The KTS1677A in the OFF state can block voltages on the VIN/VOUT pin of up to 30V and prevent reverse currents. Utilizing two KTS1677A Load Switches allow dual power inputs to connect to the same downstream device. The KTS1677A is available in an advanced, fully “green” compliant, 2.57mm x 1.57mm, Wafer-Level Chip-Scale Package (WLCSP).
