TUSB320LAIRWBR

TUSB320LAIRWBR is a Texas Instruments USB Type-C configuration channel logic and port controller in X2QFN-12 — for Type-C sink, source and dual-role ports: supports DFP, UFP and DRP modes with I2C and GPIO control. It handles CC detection, plug orientation and current advertisement in hardware, so the MCU is freed from Type-C state-machine firmware and port bring-up time drops. Selection advice: the RWB code is the X2QFN-12 tape-and-reel variant of the TUSB320LAI family — for full Power Delivery negotiation pair it with a PD controller such as the TPS65988; the TUSB320 alone covers non-PD Type-C logic and is the lower-cost path. Parameters verified against Texas Instruments documentation.

Sourcing note

Confirm interface standard, isolation requirement, package and board-level compatibility.

Before you request a quote

Confirm enable polarity (LAI vs HAI)
TUSB320LAI is enabled only with EN_N pulled low: the pin has a 1.1 MΩ internal pull-up to VDD that disables the device, so a floating or high EN_N leaves the part in shutdown (still maintaining Rd on the CC pins), and an externally driven EN_N must be held low for at least 50 ms after VDD reaches its valid level. TUSB320HAI is the mirror image — internal pull-down, EN high to enable, floating leaves it off. The two are pin-for-pin in the same X2QFN-12 — a wrong-variant substitution silently inverts your enable logic.
Check the rail before relying on 3 A advertisement
The supply range starts at 2.7 V, but the 330 µA (3 A) Rp advertisement requires VDD ≥ 3.5 V. Confirm the rail voltage in the design before quotation.
