Description and Introduction

RESET CIRCUIT The STM812MW16F is a microprocessor supervisory circuit manufactured by STMicroelectronics.  

**Key Features:**  
- **Voltage Monitoring:** Monitors VCC for microprocessors and digital systems.  
- **Reset Output:** Provides a reset signal when VCC falls below a preset threshold.  
- **Active-Low Reset:** Open-drain or push-pull reset output options (varies by variant).  
- **Low Power Consumption:** Typically consumes very low quiescent current.  
- **Wide Operating Voltage Range:** Supports monitoring from 1.8V to 5.5V (exact range may vary).  
- **Manual Reset Input:** Allows external push-button reset control.  
- **Temperature Range:** Industrial-grade operation (typically -40°C to +85°C).  
- **Package:** Available in SOT-23 or similar small form-factor packages.  

**Applications:**  
- Microprocessor and microcontroller-based systems.  
- Embedded systems requiring reliable power monitoring.  
- Industrial, automotive, and consumer electronics.  

For exact specifications (threshold voltages, timing, etc.), refer to the official STM812MW16F datasheet from STMicroelectronics.

Application Scenarios & Design Considerations

RESET CIRCUIT

Alternative Part Number

  • MAX811MEUS+T --: Pin-compatible microprocessor supervisory circuit with manual reset, same 4.63V/4.65V threshold class and active-low push-pull reset, widely used as a direct STM812 substitute.
  • TPS3808G33DBVR --: Adjustable-threshold supervisor with manual reset input in SOT-23, functionally equivalent reset monitoring solution with low quiescent current.
  • MCP1316MTB29E/TO --: Voltage supervisor with manual reset and active-low reset output in a small package, suitable drop-in alternative for reset monitoring applications.
