Description and Introduction

3V Supervisor with Battery Switchover The STM804SM6E is a voltage detector manufactured by STMicroelectronics.  

### **Specifications:**  
- **Type:** Voltage Detector  
- **Number of Detectors:** 1  
- **Detection Voltage Options:** Adjustable or fixed (specific voltage depends on variant)  
- **Output Type:** Active Low / Open Drain  
- **Operating Voltage Range:** Typically 1.1V to 5.5V  
- **Quiescent Current:** Low power consumption (exact value depends on variant)  
- **Package:** SOT-23-6  

### **Descriptions:**  
The STM804SM6E is a precision voltage monitoring IC designed to detect power supply voltage drops below a predefined threshold. It is commonly used in battery-powered devices, microcontrollers, and power management systems to ensure safe operation by triggering a reset or alert signal when the voltage falls below the set level.  

### **Features:**  
- **Precision Voltage Monitoring:** Ensures accurate detection of voltage levels.  
- **Low Power Consumption:** Suitable for battery-operated applications.  
- **Compact Package:** SOT-23-6 for space-constrained designs.  
- **Wide Operating Voltage Range:** Supports various power supply levels.  
- **Reliable Reset Function:** Helps prevent system malfunctions due to undervoltage conditions.  

For exact detection voltage options and detailed electrical characteristics, refer to the official STMicroelectronics datasheet.

Application Scenarios & Design Considerations

3V Supervisor with Battery Switchover

Alternative Part Number

  • MAX811SEUS+T --: Pin-compatible 4-pin supervisor with similar reset threshold and active-low push-pull reset, widely used as a direct substitute for STM804 series.
  • TPS3808G01DBVR --: Adjustable-threshold supervisor in SOT-23-6 with programmable reset delay, offering comparable monitoring function and low power consumption.
  • MCP131T-300E/TO --: 3-pin voltage supervisor with 3.0V threshold and active-low reset, suitable drop-in replacement for basic reset monitoring applications.
