Description and Introduction

Low Power Reset Circuit The part **STM1817RWX7F** is manufactured by **STMicroelectronics (ST)**.  

### **Specifications:**  
- **Type:** Voltage Detector / Reset IC  
- **Voltage Threshold:** Adjustable or fixed (specific value depends on variant)  
- **Output Type:** Active-Low Reset  
- **Operating Voltage Range:** Typically 1.0V to 5.5V (exact range may vary)  
- **Quiescent Current:** Low power consumption (exact value depends on variant)  
- **Package:** SOT-23-5 (or similar small form factor)  
- **Temperature Range:** Industrial (-40°C to +85°C) or wider depending on variant  

### **Descriptions & Features:**  
- Monitors system voltage and provides a reset signal when voltage falls below a threshold.  
- Ensures proper microcontroller/system initialization during power-up/down.  
- Low power consumption for battery-operated applications.  
- Hysteresis for noise immunity.  
- Compact package suitable for space-constrained designs.  

For exact threshold voltage, quiescent current, and other detailed parameters, refer to the official **STMicroelectronics datasheet** for **STM1817RWX7F**.

Application Scenarios & Design Considerations

Low Power Reset Circuit

Alternative Part Number

  • MAX6717UKRWD3+T --: Supervisory circuit with similar reset threshold and active-low open-drain reset output, pin-compatible function in SOT23-5, widely available alternative.
  • TPS3808G01DBVR --: Adjustable-threshold voltage supervisor with open-drain reset, low quiescent current, and SOT23-5 package; can be configured to match the 2.63V threshold.
  • MCP1316T-27FE/OT --: Voltage supervisor with 2.7V-class threshold and open-drain active-low reset in SOT23-5, offering comparable monitoring behavior for 3.3V systems.
