The chip utilizes 16 pins to manage power, control signals, and input/output channels:
Pins that connect external resistors and capacitors to set the operating frequency.
Capable of handling high-frequency resonance mode switching, essential for driving IGBTs in induction heating.

: Fixed 5.0V output variant with up to 1.0A maximum load current Quiescent Current Consumption : Ultra-low 10 A typical baseline
For standard logical layout repairs, the component maintains compatibility parameters alongside common industrial logic gates like the . To prevent hardware initialization errors caused by degraded internal parameters, always seek out fresh factory inventory (marked "NEW") rather than long-stored surplus batches.

Manage operational modes and signal processing tasks. Key Functions & Applications
Necessary on the CS and RST lines to prevent accidental triggers from floating signals.
To prevent massive voltage drops and localized thermal spikes on startup, the chip integrates a dedicated soft-start (SS) routine. System designers connect a small capacitor to Pin 10. This controls how fast the internal reference voltage climbs, preventing inductive overload during power-up sequences. 2. Advanced Multi-Channel Multiplexing
