The "HIGHWAY09A" is an integrated circuit (IC) primarily used in LED lighting control, specifically as a linear constant-current LED driver. While a full PDF datasheet is often found on specialty electronics vendor sites, Key Specifications & Features

void setup() Wire.begin(); // Set all pins as output Wire.beginTransmission(AW9523_ADDR); Wire.write(0x04); // Config port 0 Wire.write(0x00); Wire.write(0x05); // Config port 1 Wire.write(0x00); Wire.endTransmission();

Output Formula

[ V_OUT = \fracR3R1 \times (V_SHUNT+ - V_SHUNT-) ]

| Parameter | Min | Max | Unit | |-------------------------|----------|----------|-------| | Supply Voltage (VCC) | -0.3 | +7.0 | V | | Bus Pins (A/B or CANH/L)| -60 | +60 | V | | Logic Pins (R, D, RE, DE)| -0.3 | VCC+0.3 | V | | Junction Temperature | -40 | +150 | °C | | Storage Temperature | -65 | +150 | °C |

Caution: Continuous operation near maximum ratings is not recommended.

Low Quiescent Current: Approximately 10μA, making it efficient for low-power standby modes.

Pins for Current Sensing (RCS), Soft Start (ST), and Overvoltage Protection (OVP). Common Applications

Signal Management: Bridges communication between microcontrollers and high-speed sensors.
