Built-in protection against over-current, over-temperature, and over-voltage .
Used for Current Sensing , Soft Start functionality, and Overvoltage Protection timing. 3. Common Applications
Given that “Highway09a” is not an official manufacturer part number (e.g., from Texas Instruments, NXP, or Microchip), it most commonly corresponds to the module or a generic 16-channel I²C to GPIO/LED driver board based on the AW9523 (or similar, such as the TCA6416 or PCA9555). The following piece focuses on the core IC behind that module.
If running near the 1A limit at high input voltages, ensure adequate airflow or a small heatsink, as PDIP packages have limited thermal dissipation. highway09a ic datasheet
