Description

KTU1125 integrates two high current power switches, a pair of high bandwidth MUX switches and two low current switches with VCONN option. These switches are optimized to protect VBUS, SBU and CC in a USB Type-C Port. KTU1125 provides a compact protection solution to USB Type-C applications by eliminating the dependence on external components.

VBUS and CC switches can withstand up to ±100V and ±25V surge, respectively. All switch inputs are protected against IEC61000-4-2 Level 4. Additional protection features including, but not limited to, soft-start, over-voltage protection, true reverse current blocking, over-current protection, short-circuit protection and over-temperature protection.

KTU1125 is packaged in advanced, fully “green” compliant, 2.76 x 4.49mm, 39-bump Wafer-Level Chip-Scale Package (WLCSP).
