Description and Introduction

Reset + Watchdog The STM6823TWY6F is a microprocessor supervisory circuit manufactured by STMicroelectronics. Below are its key specifications, descriptions, and features:

### **Specifications:**
- **Manufacturer:** STMicroelectronics (STM)  
- **Part Number:** STM6823TWY6F  
- **Type:** Voltage Monitor / Supervisor  
- **Package:** SOT-23-5  
- **Operating Voltage Range:** 1.6V to 5.5V  
- **Reset Threshold Options:** Adjustable or fixed (factory-set)  
- **Reset Timeout Period:** Typically 140ms (adjustable with external capacitor)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Quiescent Current:** Low (typically 5µA)  

### **Descriptions:**  
The STM6823TWY6F is a precision voltage supervisor designed to monitor system voltage levels and provide a reset signal to a microprocessor or microcontroller when the supply voltage falls below a preset threshold. It ensures reliable system operation by holding the reset signal active until the voltage stabilizes.  

### **Features:**  
- **Low-Power Operation:** Ideal for battery-powered applications.  
- **Manual Reset Input:** Allows external push-button reset control.  
- **Adjustable or Fixed Threshold:** Supports both factory-programmed and user-adjustable reset thresholds.  
- **Power-On Reset (POR):** Ensures proper initialization at power-up.  
- **Small Form Factor:** SOT-23-5 package for space-constrained designs.  
- **Wide Supply Voltage Range:** Compatible with 1.6V to 5.5V systems.  

This device is commonly used in embedded systems, industrial controls, and consumer electronics where reliable voltage monitoring is critical.  

(Note: Always refer to the official datasheet for detailed specifications and application guidelines.)

Application Scenarios & Design Considerations

Reset + Watchdog

Alternative Part Number

  • MAX6823TUK+ --: Pin-compatible supervisor with similar reset threshold and watchdog function, widely available and directly interchangeable in most designs.
  • TPS3823-33DBVR --: Low-power voltage supervisor with watchdog and manual reset, comparable threshold and package, good second-source option.
  • CAT823TTDI-GT3 --: Supervisory circuit with watchdog timer and manual reset in SOT-23, functionally similar and cost-effective alternative.
