Description and Introduction

4-Pin Microprocessor Power Supply Supervisors with Manual Reset The **CAT812RTBI-GT3** is a voltage supervisor IC manufactured by **ON Semiconductor**. Here are its key specifications:

- **Function**: Monitors system voltage levels and provides a reset signal when the voltage falls below a preset threshold.
- **Voltage Threshold Options**: Available in various fixed threshold voltages (specific values depend on the variant).
- **Output Type**: Push-pull or open-drain (depends on the variant).
- **Operating Voltage Range**: Typically 1.0V to 5.5V.
- **Reset Timeout Period**: Adjustable or fixed (depending on the variant).
- **Package**: SOT-23-3 (small outline transistor package).
- **Operating Temperature Range**: -40°C to +85°C (industrial grade).
- **Applications**: Used in microcontrollers, DSPs, and other digital systems requiring voltage monitoring.

For exact threshold voltages and detailed electrical characteristics, refer to the official datasheet from ON Semiconductor.

Description and Introduction

4-Pin Microprocessor Power Supply Supervisors with Manual Reset The CAT812RTBI-GT3 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.
- **Supply Voltage Range**: 1.8V to 5.5V.
- **Reset Threshold Options**: Available in fixed (1.8V, 2.5V, 2.7V, 2.93V, 3.0V, 3.3V, 5.0V) or adjustable versions.
- **Reset Timeout Period**: 140ms (minimum).
- **Output Type**: Active-low reset output (open-drain or push-pull, depending on variant).
- **Package**: SOT-23-5.
- **Operating Temperature Range**: -40°C to +85°C.
- **Quiescent Current**: Typically 6µA (low power consumption).
- **Manual Reset Input**: Available on some variants for external reset control.

This device is commonly used in embedded systems, computers, and other applications requiring reliable power monitoring.
