Description
KTS1652 is a low resistance, bi-directional high current load switch with over-voltage protection, overtemperature protection and integrated TVS. The integrated TVS at VBUS is rated up to IEC61000-4-5 ±200V Surge voltage and IEC61000-4-2 Level 4 Electrostatic Discharge, which protects the downstream components from abnormal input conditions.
When VBUS is greater than VUVLO_BUS, the integrated LDO provides an “always ON” power source at BUS_DET. BUS_DET voltage is regulated to typically 4.0V, regardless of the status of ENB, so to power downstream components permitting operation without an installed battery.
KTS1652 is packaged in advanced, fully “green” compliant, 2.460 x 1.967mm, 20-bump Wafer-Level Chip-Scale Package (WLCSP).
