Description and Introduction

5-Pin Supervisor with Watchdog Timer and Push-button Reset The STM6823LWY6F is a microprocessor supervisory circuit manufactured by STMicroelectronics.  

### **Specifications:**  
- **Supply Voltage (VCC):** 1.6V to 5.5V  
- **Reset Threshold Voltage Options:** 2.32V, 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-23-5  

### **Descriptions and Features:**  
- Monitors microprocessor power supply voltage and generates a reset signal when VCC falls below the threshold.  
- Guaranteed reset output valid down to VCC = 1V.  
- Low quiescent current (6µA typical).  
- Push-pull active-low reset output.  
- No external components required.  
- Suitable for battery-powered and low-voltage applications.  
- Industrial-grade reliability.  

For detailed datasheets, refer to STMicroelectronics' official documentation.

Application Scenarios & Design Considerations

5-Pin Supervisor with Watchdog Timer and Push-button Reset

Alternative Part Number

  • MAX6823LUK+T --: Same function family: low-voltage supervisor with manual reset and watchdog, similar reset threshold and active-low push-pull output; pin-compatible SOT-23-5 package makes it a strong drop-in candidate.
  • TPS3823-33DBVR --: 3.3V supply voltage supervisor with manual reset input and watchdog timer in SOT-23-5, offering comparable reset threshold and output behavior for supply monitoring applications.
  • CAT823LSDI-GT3 --: Low-power voltage supervisor with manual reset and watchdog in a small SOT-23 package, providing similar reset threshold and active-low reset output as a cost-effective alternative.
