A standard datasheet typically includes absolute maximum ratings, timing diagrams, and electrical characteristics that are not fully provided in the manufacturer’s snapshot. However, there are still viable ways to locate technical documentation:
: Main power supply input. The device features a wide input threshold to handle voltage swings common in main line AC-rectified power stages.
: Monitors the AC mains current draw via a current transformer or shunt resistor to prevent overcurrent states. Voltage Sensing ( VINcap V sub cap I cap N end-sub Highway09a Ic Datasheet Pdf

Packaging and Ordering Information
The Highway09a is engineered as a high-reliability, low-latency communication and signal processing IC. It bridges the gap between high-speed peripheral data streams and central processing units (CPUs/MCUs). Key Features : Monitors the AC mains current draw via
Maintain a split between the Analog Ground (AGND) and Digital Ground (GND) planes directly beneath the IC. Tie them together at a single "star ground" point under the thermal pad of the package to eliminate ground loops. Typical Reference Design Schema
Typically ranges from 3.3V to 5.5V, making it compatible with both legacy 5V systems and modern 3.3V low-power microcontrollers. Key Features Maintain a split between the Analog
The HIGHWAY09A is versatile and used across various sectors:
The HIGHWAY09A, manufactured by Holtek, is a specialized 16-pin IC designed for high-performance motor control, power management, and signal processing in demanding industrial and automotive applications. It features robust overcurrent protection, soft-start functionality, and is widely applied in smart traffic infrastructure and control systems. For technical specifications, visit Jotrin Electronics
: Constantly monitors the system's rail voltage. If the input exceeds safe boundaries, it triggers an immediate shutdown mechanism.
: It manages Pulse Width Modulation (PWM) signals to regulate power delivery to the cooking vessel, ensuring efficient and smooth heating. DIP-16 Package Benefits HighWay09A
