Description and Introduction

3V Supervisor with Battery Switchover The STM805SM6F is a microprocessor supervisory circuit from STMicroelectronics designed to monitor the power supply voltage of microprocessor and digital systems.  

### **Key Features:**  
- **Voltage Monitoring:** Monitors 3V, 3.3V, and 5V power supplies.  
- **Reset Threshold Accuracy:** ±1.5% (typical).  
- **Active-Low Reset Output:** Open-drain or push-pull configuration.  
- **Reset Timeout Period:** Typically 140ms (fixed).  
- **Low Supply Current:** 8µA (typical).  
- **Operating Voltage Range:** 1V to 5.5V.  
- **Temperature Range:** -40°C to +125°C.  
- **Package:** SOT-23-6.  

### **Applications:**  
- Microprocessor and microcontroller systems.  
- Embedded controllers.  
- Automotive electronics.  
- Industrial equipment.  

### **Description:**  
The STM805SM6F ensures proper system operation by generating a reset signal when the supply voltage falls below a preset threshold. It remains in reset until the voltage stabilizes above the threshold for the specified delay period.  

For detailed specifications, refer to the official STMicroelectronics datasheet.
