The HIGHWAY09A IC features a highly specialized 16-pin architecture tailored to manage resonance mode switching and power regulation loops. Below is the step-by-step pin layout and assignment map:

Provides power specifically for the motor driving circuit. GND (Ground Reference): Common ground for the IC.

Generates the high-speed gating signals delivered to the external IGBT (Insulated-Gate Bipolar Transistor) or power MOSFET.

Works with RT to shape the reference triangle and sawtooth oscillator waves. 4 CS Analog Input
