Description and Introduction

4-Pin Microprocessor Power Supply Supervisors with Manual Reset The CAT811MTBI-GT3 is a microprocessor (μP) supervisory circuit manufactured by **CATALYST SEMICONDUCTOR (now part of ON Semiconductor)**. Here are its key specifications:  

- **Function**: Monitors μP power supply and resets the system during power-up, power-down, or brownout conditions.  
- **Reset Threshold Voltage**: Adjustable (via external resistors) or fixed options (e.g., 2.93V, 3.08V, etc.).  
- **Output Type**: Active-low reset signal (open-drain or push-pull, depending on variant).  
- **Operating Voltage Range**: Typically **1.2V to 5.5V**.  
- **Reset Timeout Period**: Fixed (e.g., 140ms, 280ms) or adjustable.  
- **Package**: SOT-23-5.  
- **Temperature Range**: Industrial (-40°C to +85°C).  
- **Features**: Low quiescent current, manual reset input (MR), and immunity to short voltage transients.  

For exact threshold voltages or variant-specific details, refer to the official datasheet.
