Kinetic Technologies Simplifies USB Type-C Dual Role Port Design with 5A/100W, Power Delivery Protection Switch KTS1865 with Single-Path Sink/Source Capability
Power management and video/audio interface IC leader Kinetic Technologies announced the industry's first integrated USB Type-C Power Delivery Protection Switch that simplifies and shrinks existing discrete designs in Dual Role Port applications(DRP applications) ; a crucial feature in today's flagship notebook computers and docking stations. By integrating a bidirectional, reverse-blocking "ideal diode," low resistance MOSFET switch, and multiple sensing and protection features, the KTS1865 can reduce board space, minimize the bill-of-materials (BOM), and enhance system reliability by helping to enable robust protection against abnormal operating conditions.
"The KTS1865 is a device at the forefront of protection switches that can finally allow designers to simplify their Dual Role Port designs, and at the same time, can provide a reliable, cost-effective, and robust solution," said Erik Ogren, Kinetic Technologies' Senior Director of Marketing. "In existing designs, customers must often use one current sink and one current source device per port. When the USB port is in sink mode, the source device is not needed, and vice versa. Kinetic designers using our industry leading IP for both sink and source switches have combined both functions into a single switch without compromise. Customers appreciate the lower component count and the space savings this can provide."
The KTS1865 is a low resistance, high-current, bidirectional load switch optimized to protect USB Type-C Power Delivery (PD) ports that sink and/or source up to 100W at 20V, while at the same time withstand 29V on VBUS. Mode control is provided by two logic pins that enable or disable the switch, while also setting the device into either SINK or SOURCE mode. Slew-rate controlled turn-on with current limiting is designed to prevent excessive large in-rush currents while maintaining Fast Role Swap (FRS) capability. Operating from an input voltage range of 3V to 23V, the KTS1865 integrates a port-side TVS for IEC surge and ESD Level 4 protection. It also includes several additional protection features including overvoltage protection, "ideal diode" reverse current protection with fast recovery, over-current protection, programmable current limit, and over-temperature protection. The "ideal diode" reverse current protection is also bidirectional and automatically oriented to match the switch's logic-controlled sink or source mode, making it possible for two or more charging ports in a "power OR" configuration to be connected to a single charger without back-feeding the lower voltage input source.
The single-path sink/source switch architecture of the KTS1865 is particularly well suited to meet the system design challenges in docking stations, conferencing systems, and charger-per-port fnotebook computers.
Packaged in a small 2.64 x 2.14mm, 20-bump Wafer-Level Chip-Scale Package (WLCSP).
