Description and Introduction

3-Pin Microprocessor Power Supply Supervisors The CAT809STBI-T3 is a microprocessor (μP) supervisory circuit manufactured by ON Semiconductor. It is designed to monitor the power supply voltage in microprocessor-based systems and provide a reset signal when the voltage falls below a specified threshold.  

Key specifications:  
- **Reset Threshold Voltage**: 2.93V (typical)  
- **Operating Voltage Range**: 1.1V to 5.5V  
- **Output Type**: Active-low reset (open-drain)  
- **Reset Timeout Period**: 140ms (minimum)  
- **Package**: SOT-23-3  
- **Operating Temperature Range**: -40°C to +85°C  
- **Applications**: Microprocessor and microcontroller systems, embedded controllers, automotive systems  

This device ensures proper system initialization and prevents erratic operation during power-up, power-down, or brownout conditions.

Description and Introduction

3-Pin Microprocessor Power Supply Supervisors The **CAT809STBI-T3** is a **voltage supervisor IC** manufactured by **CATALYST SEMICONDUCTOR (now part of ON Semiconductor)**.  

### **Key Specifications:**  
- **Function:** Reset monitor for microprocessors and digital systems  
- **Voltage Threshold Options:** Available in multiple fixed threshold voltages (e.g., 2.63V, 3.08V, 4.38V, etc.)  
- **Output Type:** Active-low reset signal (open-drain or push-pull, depending on variant)  
- **Operating Voltage Range:** Typically **1.1V to 5.5V**  
- **Reset Timeout Period:** Fixed delay (typically 140ms or 280ms, depending on variant)  
- **Package:** **SOT-23-3** (small outline transistor package)  
- **Temperature Range:** **-40°C to +85°C** (industrial grade)  
- **Low Quiescent Current:** Typically **5µA** (low power consumption)  

### **Applications:**  
- Microprocessor and microcontroller reset circuits  
- Power supply monitoring in embedded systems  
- Battery-powered devices  

For exact threshold voltage and output configuration, refer to the specific part number suffix (e.g., **CAT809STBI-T3** may have a fixed threshold; datasheet confirmation is required).
