Description and Introduction

4-Pin Microprocessor Power Supply Supervisors with Manual Reset The **CAT811TTBI-GT3** is a microprocessor (μP) supervisory circuit manufactured by **CATALYST SEMICONDUCTOR (now part of ON Semiconductor)**. Below are its key specifications:

1. **Function**: Monitors microprocessor power supply voltage and resets the μP during power-up, power-down, or brownout conditions.
2. **Reset Threshold Voltage**: Fixed at **4.38V** (typical).
3. **Operating Voltage Range**: **1.0V to 5.5V**.
4. **Reset Timeout Period**: **140ms** (minimum).
5. **Output Type**: Active-low reset (**/RESET**).
6. **Package**: **SOT-23-3** (3-pin).
7. **Temperature Range**: **-40°C to +85°C** (industrial grade).
8. **Quiescent Current**: **6μA** (typical at 3.3V).
9. **Manual Reset Input**: Not available (this variant lacks a manual reset pin).
10. **Applications**: Embedded systems, servers, networking equipment, and other critical μP-based designs requiring reliable power monitoring.

For exact tolerances and additional details, refer to the official datasheet.
