Description and Introduction

3-Pin Microprocessor Power Supply Supervisors The CAT809MTBI-GT3 is a microprocessor supervisory circuit manufactured by ON Semiconductor. It is designed to monitor the power supply voltage of microprocessors and digital systems. Key specifications include:

- **Voltage Threshold Options**: Available in fixed voltage thresholds (e.g., 2.63V, 3.08V, 4.38V, etc.).
- **Reset Timeout Period**: Typically 140ms (minimum).
- **Operating Voltage Range**: 1.0V to 5.5V.
- **Low Quiescent Current**: Typically 5µA.
- **Output Type**: Active-low reset output (open-drain or push-pull, depending on variant).
- **Package**: SOT-23-3.
- **Temperature Range**: -40°C to +85°C (industrial grade).
- **Features**: Manual reset input, glitch immunity, and guaranteed reset assertion down to VCC = 1.0V.

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