Description and Introduction

3-Pin Microprocessor Power Supply Supervisors The **CAT809STBI-GT3** is a microprocessor (μP) supervisory circuit manufactured by **CATALYST SEMICONDUCTOR (now part of ON Semiconductor)**. Here are its key specifications:  

- **Function**: Monitors microprocessor power supply and provides a reset signal during power-up, power-down, or brownout conditions.  
- **Reset Threshold Voltage**: Adjustable (factory-set options available).  
- **Output Type**: Active-low RESET signal.  
- **Operating Voltage Range**: Typically **1.1V to 5.5V** (varies by variant).  
- **Reset Timeout Period**: Fixed (e.g., 140ms, model-dependent).  
- **Package**: **SOT-23-3** (small form factor).  
- **Features**: Low quiescent current, manual reset capability (if applicable), and immunity to brief voltage transients.  

For exact threshold voltages or custom configurations, refer to the datasheet or ON Semiconductor’s documentation.

Description and Introduction

3-Pin Microprocessor Power Supply Supervisors The **CAT809STBI-GT3** is a microprocessor supervisory circuit from **ON Semiconductor** (formerly part of **Catalyst Semiconductor**).  

### **Key Specifications:**  
- **Function:** Monitors microprocessor power supply voltages and resets the system during power-up, power-down, or brownout conditions.  
- **Reset Threshold Voltage:** Adjustable or fixed (exact value depends on variant; check datasheet for specific model).  
- **Output Type:** Active-low reset signal (**/RESET**).  
- **Supply Voltage Range:** Typically **1.2V to 5.5V** (varies by model).  
- **Operating Temperature Range:** **-40°C to +85°C**.  
- **Package:** **SOT-23-3** (small outline transistor package).  
- **Manual Reset Input:** Some variants include a manual reset pin (**MR**).  
- **Applications:** Embedded systems, microcontrollers, DSPs, and other digital systems requiring reliable power monitoring.  

For exact specifications (e.g., reset threshold voltage, timing), refer to the **official datasheet** from **ON Semiconductor**.
