When the junction temperature exceeds 150°C, the Highway 09 reduces output current linearly (thermal foldback). At 160°C, it shuts down completely. Once cooled by 15°C (hysteresis), it restarts automatically.
Some versions of the chip support I²C communication between the main microcontroller and the user interface panel. This has been used by hobbyists to interface with induction cookers using an ESP32 running Tasmota, enabling smart home integration.
Based on reverse‑engineered schematics, a typical circuit includes:
Some speculated that it was a custom-designed chip for a specific application, while others believed it was a proof-of-concept that never made it to production. The mystery surrounding the Highway 09 IC only deepened. highway 09 ic datasheet
Although less common, the chip has been integrated into systems such as:
