Kinetic Technologies KTS1865 USB SPR Bi-Directional Safety Switches

Kinetic Technologies KTS1865 USB SPR Bi-Directional Safety Switches are low-resistance, high-current load switches optimized to protect USB Standard Power Range (SPR) Type-C™ ports that sink up to 130W at 20V and source up to 100W at 20V. Protection features include soft-start, over-voltage protection, “ideal diode” reverse-current protection with fast recovery, short-circuit protection, over-current protection, programmable current limit protection, over-temperature protection, integrated TVS for IEC surge, and ESD protection. Other features include a POK Safe LDO, FLT open-drain output flag, fast soft start mode for USB fast role swap, and active discharge for the VBUS. The EN1 and EN2 logic inputs enable/disable the switch and set the ISINK vs. ISOURCE operating mode. The Kinetic Technologies KTS1865 is packaged in advanced, fully Green compliant, 2.71mm x 2.16mm, 20-bump Wafer-Level Chip-Scale Package (WLCSP).
