TPS65983BAZBHR

TPS65983B is a highly integrated standalone USB Type-C and Power Delivery (PD) controller optimized for notebook applications. TPS65983B integrates a fully managed power path with robust protection features to provide a complete USB-C PD solution. TPS65983B includes a high-speed multiplexer that responds to USB Type-C cable orientation based on the CC pin. The multiplexer passes sideband use data for alternate modes. TPS65983B features a BGA MicroStar Junior package with 0.5mm pitch and through-holes, compatible with all pins. The mixed-signal front-end on the CC pins provides Type-C power default (500mA), 1.5A, or 3A current levels, detects cable insertion events, determines USB Type-C cable orientation, and autonomously negotiates USB PD contracts following the specified Biphase Mark Coding (BMC) and Physical Layer (PHY) protocols. The port power switch supports up to 3A downstream current for legacy USB power and Type-C USB power at 5V. An additional bidirectional switch path supports up to 3A at voltages up to 20V when the USB PD power port operates as a source (host), sink (device), or dual-role power port. TPS65983B can also operate as an Upstream Facing Port (UFP), Downstream Facing Port (DFP), or dual-role data port. The port data multiplexer enables USB 2.0 HS data transfer between the port and the top or bottom D+/D− signal pairs, and includes a USB 2.0 low-speed endpoint. The Sideband Use (SBU) signal pair can also be used for auxiliary or alternate mode communication (e.g., DisplayPort or Thunderbolt). The power management circuit is powered by the system's internal 3.3V supply, while using VBUS for startup and power negotiation for battery-depleted or battery-absent conditions.
