- **Caution**: 

### Q: What is Protection Logic in electronic systems?
**A**: Protection Logic refers to the circuitry within a Protection IC or Analog Front-End (AFE) that continuously monitors system parameters like voltage, current, or temperature and activates protective measures when predefined thresholds are exceeded to prevent damage.

### Q: What components are typically included in Protection Logic BOM?
**A**: A typical Bill of Materials for Protection Logic includes comparators to detect threshold violations, latches or flip-flops to maintain protection states, and logic gate arrays that implement the decision-making algorithms for triggering appropriate protective actions.

### Q: How does Protection Logic enhance system reliability?
**A**: Protection Logic enhances reliability by providing real-time monitoring and automated response to fault conditions, preventing catastrophic failures in electronic systems through features like overvoltage protection, thermal shutdown, and current limiting.
