Description and Introduction

3V Supervisor with Battery Switchover The **STM806SM6F** is a microprocessor supervisory circuit from **STMicroelectronics**.  

### **Manufacturer:** STMicroelectronics  

### **Specifications:**  
- **Supply Voltage (VCC):** 1.8V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (2.63V, 2.93V, 3.08V, 4.38V, 4.63V)  
- **Reset Timeout Period:** 140ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-6  

### **Descriptions and Features:**  
- Monitors microprocessor power supply and generates a reset signal if voltage drops below a preset threshold.  
- Low quiescent current (typically 5µA).  
- Manual reset input for user-initiated reset.  
- Power-on reset (POR) ensures proper system initialization.  
- Available in fixed and adjustable threshold versions.  
- Suitable for battery-powered and low-voltage applications.  

For detailed datasheets, refer to **STMicroelectronics' official documentation**.

Application Scenarios & Design Considerations

3V Supervisor with Battery Switchover

Alternative Part Number

  • MAX809SEUR+T --: Pin-compatible supervisor with similar reset threshold and active-low push-pull output; widely available and a common drop-in replacement for STM806 series.
  • MCP130T-300I/TT --: 3-pin voltage supervisor with comparable reset threshold and active-low output, suitable for the same monitoring function in most designs.
  • APX803S-30SA-7 --: Low-cost 3-pin reset supervisor with similar threshold and open-drain/push-pull options, offering a cost-effective alternative with good availability.
