USB Type-C controller with dual-rail supply
The Texas Instruments TPS65981ABTRTQR is a USB Type-C controller IC that handles cable orientation detection, role negotiation, and power delivery policy for USB-C ports. It operates from either a 3.3V or 5V supply rail — the dual-voltage input simplifies system power architecture by letting the controller share a common rail with the rest of the USB subsystem.
Industrial temperature grade — factory-floor ready
The 105°C ceiling covers most non-hermetic industrial environments without requiring active cooling.
The base product number TPS65981 anchors a family of Type-C controllers; this -ABT variant carries the latest die revision and firmware mask.
