- **Output Type**: Active-low reset output (open-drain or push-pull, depending on variant).  
- **Operating Voltage Range**: Typically **1.8V to 5.5V**.  
- **Reset Timeout Period**: Fixed delay (e.g., 140ms, 280ms, or adjustable via capacitor).  
- **Package**: SOT-23 (3-pin or 5-pin, depending on variant).  
- **Temperature Range**: Industrial (**−40°C to +85°C**).
