CAT811STBI-GT3

The CAT811STBI-GT3 is a precision voltage supervisory IC designed to monitor the power supply in microprocessor-based systems. Its primary function is to ensure that the system operates within safe voltage levels by providing a reset signal to the microprocessor during power-up, power-down, and brownout conditions. The device features a fixed threshold voltage that triggers a reset when the monitored voltage falls below a specified level, ensuring that the microprocessor remains in a known state and preventing it from executing erroneous operations. The CAT811STBI-GT3 is commonly used in applications requiring reliable system resets, including consumer electronics, industrial equipment, and communication devices. With its low power consumption and compact packaging, it offers an efficient and space-saving solution for enhancing system reliability.

The CAT811STBI-GT3 is a supervisory circuit designed to monitor power supply voltages in microprocessor systems. Key features include:
1. Voltage Monitoring: It monitors a single power supply and asserts a reset signal when the voltage drops below a predefined threshold, ensuring microprocessor stability.

2. Reset Functionality: Provides a reset output to prevent operation under low voltage conditions, with an active-low reset output.
3. Precision Threshold: Offers accurate voltage threshold levels to ensure reliable system resets.
4. Low Supply Current: Features a low quiescent current, making it energy-efficient and suitable for battery-powered applications.
5. Small Package: Available in a compact SOT-23 package, optimizing space on printed circuit boards.
6. Temperature Range: Operates effectively across a broad temperature range, catering to various environmental conditions.
These features make the CAT811STBI-GT3 an ideal choice for ensuring system stability in electronic applications sensitive to voltage fluctuations.

The CAT811STBI-GT3 is a supervisory circuit in a SOT-143 package. This type of package is a small-outline transistor package with four leads, suitable for space-constrained applications.

The CAT811STBI-GT3 is a voltage supervisor IC manufactured by ON Semiconductor. It typically comes in a SOT-23-3 package, which means it has 3 pins. The primary function of this IC is to monitor the power supply voltage in digital systems and provide a reset signal when the voltage drops below a specified threshold, ensuring proper startup and operation of microcontrollers and other digital systems.
The pin configuration is generally as follows:
1. Pin 1 (GND): Ground connection.
2. Pin 2 (RESET): Output pin that provides the reset signal. This pin typically goes low when the monitored voltage falls below the threshold and remains low until the voltage returns to a safe level and a specified reset timeout period has elapsed.
3. Pin 3 (VCC): Supply voltage input. This is the voltage being monitored.
The CAT811STBI-GT3 helps prevent microcontroller lock-up and data corruption by ensuring that the system only operates when there is a stable power supply.
