Kinetic Technologies, a power management solutions provider, expands its portfolio with the introduction of the KTS1800, a high-performance USB VBUS safety management load switch designed for USB Type-C PD 3.1 Extended Power Range (EPR) applications. Engineered to handle up to 312W in sink-mode and 240W in source-mode, the KTS1800 ensures superior power delivery, safety, and protection for high-power USB devices.
The KTS1800 features a 3V to 55V operating range and withstands input/output voltages up to 59VDC, making it ideal for USB-C EPR Notebooks, docking stations, monitors, adapters, and other high-power USB applications. Its ultra-fast 55V over-voltage protection (OVP), reverse-current protection (RCP), and integrated active transient flat-clamp voltage suppression (TVS) provide unmatched system reliability against surges, ESD events, and power fluctuations. The device functions as a Dual Role Power (DRP) port using a single power path dynamically switching between sink- and source-modes. This enables a more robust and space efficient solution in docking stations and “charger-per-port” notebook computers.
“Architecting 48V USB EPR systems is challenging for OEM system designers as the silicon ecosystem is in an early stage. New methods are needed to handle fault conditions compared to 20V USB SPR,” said Erik Ogren, Senior Director of Product Marketing at Kinetic Technologies. “KTS1800 features all of the robust system protection that Kinetic’s USB Protection IC customers have come to appreciate, with new advances to tackle specific 48V demands. One difficulty OEMs face is choosing a suitable small size TVS diode for surge protection which can adequately protect the 48V PD Controller IC. KTS1800’s flat-clamp active clamp solves that problem by protecting against input surges, while maintaining a safe voltage for downstream devices.”
KTS1800 features a 3V to 55V operating voltage range with a 59VDC max rating at VBUS and VSYS, ensuring high reliability. It supports 6.5A RMS continuous current with a low 25mΩ on-resistance. Safety features include 55V over-voltage protection, active transient voltage suppression, and surge protection (48VDC ±130V). It offers ±30kV ESD protection, short-circuit, over-current, and reverse-current protection. Additional highlights include a 3.3V POK LDO, fast role swap support, and a fault auto-retry mechanism. Operating between -40°C and 85°C, it comes in a compact 63-bump WLCSP package (4.81 x 3.79mm), ideal for space-constrained applications.
