Description
The KTS1865 is a low-resistance, high-current load switch optimized to protect USB Standard Power Range (SPR) Type-C ports that sink up to 130W at 20V and/or source up to 100W at 20V. The 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, and integrated TVS for IEC surge and ESD protection. Other features include a POK Safe LDO, !F!L!T! open-drain output flag, fast softstart mode for USB fast role swap, and active discharge for VBUS. The EN1 and EN2 logic inputs enable/disable the switch and set the ISINK vs. ISOURCE operating mode.
The KTS1865 is packaged in advanced, fully “green” compliant, 2.71 x 2.16mm, 20-bump Wafer-Level Chip-Scale Package (WLCSP).
