Microchip Technology MCP111T-240E/TT Voltage Supervisor

The MCP111T-240E/TT from Microchip Technology is a highly precise voltage supervisor device designed to keep microcontroller systems safe by monitoring the power supply voltage levels. This compact and efficient component is essential for applications that require reliable operation under varying voltage conditions, ensuring that systems remain within their operational voltage range.

With a nominal threshold voltage of 2.40V, the MCP111T-240E/TT is ideal for managing 2.5V and 3.3V systems. It offers a tight tolerance level, ensuring that the voltage supervisor acts only when necessary, thereby preventing unnecessary system resets or interruptions. The device comes in a 3-pin SOT-23 package, which is suitable for space-constrained designs, providing a space-saving solution without compromising on performance.

One of the key features of the MCP111T-240E/TT is its active-low, open-drain output. This configuration allows for a simple connection to a microcontroller's reset pin, triggering a reset sequence whenever the monitored voltage falls below the threshold. The open-drain output also enables the connection of multiple devices to a single reset line, facilitating an OR-tied configuration for monitoring several voltages simultaneously.

The MCP111T-240E/TT is characterized by its low supply current, making it an energy-efficient choice for battery-powered applications. Its quick response time ensures that systems are promptly alerted to potential power issues, allowing for immediate corrective action to be taken. Additionally, the built-in hysteresis feature helps to prevent false triggering due to transient voltage fluctuations, providing a stable and reliable supervision mechanism.

This voltage supervisor is designed to operate over an extended temperature range of -40°C to +125°C, making it suitable for industrial and automotive applications where extreme temperatures are common. The robust design and high accuracy of the MCP111T-240E/TT make it a trusted component for safeguarding critical electronic systems against the dangers of undervoltage conditions.

In summary, the MCP111T-240E/TT from Microchip Technology is an essential device for ensuring the stability and reliability of electronic systems, offering precise voltage monitoring with minimal power consumption and a compact footprint.
