According to documentation from Xecor and Jotrin , the pinout generally includes: : Power supply and motor voltage supply pins. GND : Ground reference for the circuit.

CMOS/TTL compatible digital input pin. A logic low or high on this pin drives the state of the physical bus outputs when the transmitter is enabled.
: It directly reads signals from touch buttons, controls LED displays via I2C, and generates the precise Pulse Width Modulation (PWM) signals needed to switch the main IGBT at high frequencies (typically 20-50kHz). It also monitors AC mains voltage (Pin 16), ensures the resonant circuit is synchronized (Pins 4 and 15), and constantly checks for dangerous over-current or surge conditions (Pin 1) to turn off the IGBT if needed. highway 09 ic datasheet

). Used for biased termination networks to maintain bus stability during idle periods.
: Supports manual and automated round-robin channel scanning to reduce MCU firmware dependencies. According to documentation from Xecor and Jotrin ,
If the HIGHWAY09A is unavailable, consider these alternatives (note: pin compatibility is not guaranteed):
The most reliable technical data comes from reverse engineering and community analysis, particularly from the EEVblog forum where a user successfully extracted the specifications from a HIGHWAY‑branded product page.

Exact pin assignments may vary slightly depending on the specific firmware version. For induction cooker applications, pin 1 is often connected to a voltage divider from the mains for synchronous control, while pin 3 drives the IGBT gate via a driver circuit.
Delivers up to 3A of continuous output current at a programmable 3.3V or 5.0V output with up to 93% efficiency.
