Kinetic KTU1121AEUAJ-TD USB Type-C Port Protector. Manufactured by Kinetic Technologies, this high-performance USB Type-C port protection chip is specifically designed to safeguard the CC and SBU pins of USB Type-C interfaces. As a renowned distributor of electronic components, Mingjiada Electronics offers genuine stock of this model.
KTU1121AEUAJ-TD Product Description
The KTU1121AEUAJ-TD is a USB Type-C port protector introduced by Kinetic Technologies, primarily used to safeguard device-side USB Type-C interfaces against damage from electrical events such as overvoltage (OVP) and electrostatic discharge (ESD). It incorporates four independent overvoltage protection channels (for CC1, CC2, SBU1, and SBU2 signals). Upon detecting an overvoltage event, it rapidly interrupts the signal path, thereby safeguarding downstream circuits (such as PD controllers) from damage. The device is packaged in a 20-pin TQFN (3mm x 3mm) format, supplied in tape-reel (TR) packaging, and is suitable for surface-mount device (SMD) processes.
