Highway 09 Ic: Datasheet

The Highway 09 (often referred to as HIGHWAY09A) is a versatile integrated circuit primarily used in automotive applications and appliance control systems like induction cookers. It is commonly found in a 16-pin DIP package and is designed for power regulation and motor control tasks. Key Technical Specifications

VCC/GND: Power supply pins (standard operating voltages are often between 5V and 18V for controller logic). PWM Output: Controls the IGBT or power MOSFET switching. highway 09 ic datasheet

References

  1. Sense Resistor (R_sense): Place it as close as possible to the OUT and GND pins. Use Kelvin sensing (separate traces for voltage sensing vs. current carrying) if running >1A.
  2. Ground Plane: Use a solid ground plane on the bottom layer. Connect the IC's tab (GND) to this plane with at least 4 thermal vias.
  3. Input Capacitor: C1 must be within 10mm of the VIN pin to suppress alternator ripple (100Hz to 100kHz).
  4. Trace Width: For 1A, use 1mm (40mil) traces minimum. For 1.5A, use 2mm (80mil) traces or use a solder jumper.

According to technical documentation and the Highway 09 IC Datasheet, the device typically operates within the following parameters: Operating Voltage: 2.4V to 5.5V. Operating Frequency: 32kHz to 8MHz. The Highway 09 (often referred to as HIGHWAY09A
