Product details

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.

Frequently asked questions

Is TPS65981ABTRTQR equivalent to TPS65981?

The TPS65981ABTRTQR shares the same base product number (TPS65981) and functional architecture. The -ABT suffix indicates this is the latest die revision and firmware mask. It is pin-compatible with earlier TPS65981 variants but carries updated configuration registers and PD policy engine.
