The HIGHWAY09A bridges high-voltage power electronics with low-voltage microcontroller logic. It regulates resonant-frequency switching induction coils while tracking continuous sensor feedback.
The chip serves as the primary system brain for multi-stage induction cookers. It decodes button presses, controls the cooling fan via its motor pins, and sequences the heating pulses to regulate temperature precisely. Robotics & Motion Control
