Silicon Laboratories and Korean intelligent‑tire system provider BANF have announced a partnership that embeds the company’s ultra‑low‑power BG22 Bluetooth LE system‑on‑chip into BANF’s in‑tire sensor platform. The integration enables real‑time, battery‑free processing of 4 kHz tire data, a capability that supports autonomous vehicle and connected fleet applications.
The BG22 chip delivers sub‑microwatt sleep modes and high‑resolution data handling, while Silicon Labs’ Secure Vault technology provides automotive‑grade security. BANF supplies a proprietary magnetic‑resonance wireless power transfer system that continuously powers the in‑tire sensor, allowing the sensor to collect 3‑axis acceleration, pressure, temperature and tread‑depth data at thousands of samples per second and filter key signals before transmitting alerts.
Silicon Labs’ Q4 2025 earnings, reported February 4, 2026, showed revenue of $208.2 million and a basic EPS of $0.56, beating analyst expectations of $0.54. The company’s Industrial & Commercial segment grew 37% YoY to $122.0 million, while the Home & Life segment increased 12% YoY to $87.0 million. CEO Matt Johnson noted that the company “executed well to close out 2024, with fourth‑quarter revenue nearly doubling from the same quarter one year ago,” and that sequential revenue growth is expected to resume in the first quarter of 2026.
The partnership positions Silicon Labs as a key enabler for the digitization of the automotive “last analog domain.” By providing a battery‑free, high‑resolution data stream, the solution can feed chassis control, stability systems and autonomous driving algorithms, creating new revenue opportunities through predictive maintenance, route optimization and insurance‑linked services. The collaboration aligns with Silicon Labs’ strategy of embedding low‑power wireless and security solutions into edge devices across new verticals, reinforcing its foothold in the high‑growth automotive IoT market.
