Description and Introduction

5V Supervisor with Battery Switchover The STM802MM6F is a microprocessor supervisory circuit from STMicroelectronics. Here are its key specifications, descriptions, and features:

### **Manufacturer:**  
STMicroelectronics  

### **Specifications:**  
- **Supply Voltage (VCC):** 1.0V to 5.5V  
- **Reset Threshold Voltage Options:** Adjustable or fixed (1.6V, 2.32V, 2.93V, 4.38V)  
- **Reset Timeout Period:** 140ms (typical)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** SOT-23-5  

### **Descriptions:**  
- The STM802MM6F monitors the power supply voltage of a microprocessor or digital system.  
- It asserts a reset signal when VCC falls below the preset threshold, ensuring proper system initialization.  
- It is designed for low-power applications and provides reliable power-on reset functionality.  

### **Features:**  
- **Low Quiescent Current:** Typically 5µA  
- **Manual Reset Input:** Allows external reset control  
- **Power-On Reset Delay:** Ensures stable voltage before releasing reset  
- **Small Form Factor:** SOT-23-5 package for space-constrained designs  
- **Wide Operating Voltage Range:** Supports 1.0V to 5.5V systems  

This information is based solely on the device's datasheet and technical documentation.

Application Scenarios & Design Considerations

5V Supervisor with Battery Switchover

Alternative Part Number

  • MAX6326UR29-T --: Pin-compatible voltage supervisor/reset IC in SOT-23 with similar reset threshold and active-low push-pull output, suitable drop-in replacement for supply monitoring.
  • TPS3808G30DBVR --: Low-power voltage supervisor in SOT-23 with adjustable delay and active-low reset, comparable function and package to the STM802 supervisor.
  • MCP1316T-29FE/TO --: Voltage supervisor with active-low reset in a small SOT-23 package, offering similar threshold and reset behavior for microcontroller supply monitoring.
