Description
The TPS65981 is a highly integrated stand-alone USB Type-C and Power Delivery (PD) controller optimized for notebook applications. The TPS65981 integrates fully managed power paths with robust protection for a complete USB-C PD solution. The TPS65981 integrates a high speed multiplexer which is dependent the USB Type-C cable orientation that the CC pins provide. The multiplexer passes through side-band use data for alternate modes. The TPS65981 has a QFN package for reliable manufacturing with 0.5-mm Pitch and 2-Layer PCB compatibility and has an extended (industrial) temperature range. The TPS65981 is USB PD 2.0 certified which is no longer certifiable through USB IF. Parameters
Features • This device is certified by the USB-IF for PD2.0 – PD2.0 is no longer certifiable on new designs as of June 2020 – All new designs requiring certification should use a PD3.0 compliant device – Article on PD2.0 vs PD3.0 • Fully configurable USB PD controller – Control for external DC/DC supplies through GPIO • Ex: TPS65981EVM – Port data multiplexer • USB 2.0 HS data and low speed endpoint • Sideband-use data for alternate modes – GUI tool to easily configure TPS65981 for various applications – Support for DisplayPort alternate mode – Supports industrial temperature range – For a more extensive selection guide and getting started information, please refer to www.ti.com/usb-c and E2E guide • Integrated fully managed power paths: – Integrated 5-V, 3-A, 55-mΩ sourcing switch – Integrated 5-V to 20-V, 3-A, 95-mΩ bidirectional load switch – Gate Control and current sense for external 5-V to 20-V, 5-A bidirectional switch (back-to back NFETs) – UL2367 cert#: E169910-20150728 • Integrated robust power path protection – Integrated reverse current protection, undervoltage protection, overvoltage protection, and slew rate control the high-voltage bidirectional power path – Integrated undervoltage and overvoltage protection and current limiting for inrush current protection for the 5-V/3-A source power path • USB Type-C® Power Delivery (PD) controller – 8 configurable GPIOs – BC1.2 charging support – USB PD 2.0 certified – USB Type-C specification certified – Cable attach and orientation detection – Integrated VCONN switch – Physical layer and policy engine – 3.3-V LDO output for dead battery support – Power supply from 3.3 V or VBUS source – 1 I2C primary port – 1 I2C secondary port All the evaluation(0)
