### **Descriptions:**  
The TPS3805H33QDCKRQ1 is a low-power voltage supervisor designed to monitor system voltages in automotive and industrial applications. It provides a reset signal when the supply voltage drops below a preset threshold, ensuring proper system initialization.  

### **Features:**  
- **Low Power Consumption:** Ultra-low quiescent current (1.5µA)  
- **Wide Supply Range:** Operates from 1.8V to 6.5V  
- **Automotive Qualified:** AEC-Q100 Grade 1  
- **Adjustable or Fixed Threshold:** 3.3V fixed threshold (H33 variant)  
- **Manual Reset Input:** Allows external system reset  
- **Small Package:** SC-70 (5-pin) for space-constrained designs  
- **High Accuracy:** Tight threshold tolerance (±1.5%)  

This device is suitable for battery-powered, automotive, and industrial applications requiring reliable voltage monitoring.
