MCP809T-315I/TT

The MCP809T-315I/TT is a microprocessor supervisory circuit designed to monitor and manage the power supply of microprocessor-based systems. Its primary function is to ensure that the microprocessor operates only when the supply voltage is within specified limits, thereby protecting it from low voltage conditions that could cause operational errors.
Key features of the MCP809T-315I/TT include a precision voltage reference and a comparator that monitors the voltage level. When the voltage drops below the threshold, the device generates a reset signal to the microprocessor, ensuring that it safely resets until the voltage returns to acceptable levels. This reset signal helps in avoiding unexpected behavior from the microprocessor during power fluctuations.
Additional benefits of the MCP809T-315I/TT include low power consumption, which is crucial for battery-operated devices, and a compact package design suitable for applications with limited space. It is widely used in various applications, including computers, embedded systems, and other electronic devices requiring reliable power supervision.

The MCP809T-315I/TT is a microprocessor supervisory circuit designed to monitor power supply levels in digital systems. It features a reset function that ensures the microprocessor starts in a known state upon power-up. Key features include:
1. Reset Threshold: It monitors the supply voltage and asserts a reset when it drops below 3.15V, ensuring reliable operation for systems powered by 3.3V.
2. Reset Timeout: The device provides a fixed reset timeout period of approximately 140ms, allowing the system to stabilize before commencing normal operations.
3. Low Supply Current: The MCP809T-315I/TT is energy-efficient, drawing a low quiescent current, ideal for battery-operated applications.
4. Push-Pull Output: It features a push-pull active-low reset output, simplifying interface with microprocessors without the need for external pull-up resistors.
5. Temperature Range: The device operates over an industrial temperature range of -40°C to +85°C, making it suitable for various environmental conditions.
6. Package: It is available in a compact SOT-23 package, saving board space.
These features make the MCP809T-315I/TT suitable for various applications requiring reliable microprocessor supervision.

The MCP809T-315I/TT is a microprocessor supervisory circuit packaged in a SOT-23-3 form factor. This package is a small outline transistor package with three pins, commonly used for space-efficient applications on printed circuit boards.

The MCP809T-315I/TT is a voltage supervisory device designed to monitor the power supply voltage in microprocessor systems. It has a 3-pin configuration. The primary function of this device is to ensure the proper operation of a system by asserting a reset signal whenever the monitored voltage drops below a specified threshold. This helps to prevent erratic operation or incorrect data processing when the supply voltage is insufficient.
The pins are typically configured as follows:
1. VDD (Pin 1): This is the power supply pin, which monitors the input voltage.
2. GND (Pin 2): This is the ground reference pin.
3. RESET (Pin 3): This pin outputs the reset signal. It is typically an active-low output, meaning it goes low when the monitored voltage falls below the threshold.
The MCP809T-315I/TT is used in applications where maintaining the integrity of the system upon power fluctuations is critical, such as in microcontroller-based systems.
