Description and Introduction

4-Pin Microprocessor Power Supply Supervisors The CAT811TTBI-T is a microprocessor supervisory circuit manufactured by CATALYST SEMICONDUCTOR (now part of ON Semiconductor). Here are its key specifications:

- **Function**: Monitors microprocessor power supplies and resets the system during power-up, power-down, or brownout conditions.
- **Reset Threshold Voltage Options**: Available in various fixed thresholds (e.g., 2.63V, 2.93V, 3.08V, 4.38V, etc.).
- **Reset Timeout Period**: Typically 140ms (minimum).
- **Operating Voltage Range**: 1.0V to 5.5V.
- **Quiescent Current**: Low supply current (typically 6µA).
- **Output Type**: Active-low reset output (open-drain or push-pull, depending on variant).
- **Package**: SOT-23-3.
- **Operating Temperature Range**: -40°C to +85°C.
- **Features**: Includes power-on reset (POR) generation, manual reset input (MR), and immunity to short power glitches.

For exact threshold voltage and output configuration, refer to the specific part number suffix (e.g., CAT811TTBI-GT3). Always consult the datasheet for detailed specifications.
