Microchip Technology MCP101T-300I/TT Microcontroller Supervisor

The MCP101T-300I/TT is a highly reliable voltage supervisory device designed and manufactured by Microchip Technology, a leading provider of microcontroller and analog semiconductors. This supervisor IC is specifically engineered to keep microcontroller-based systems safe by monitoring the power supply voltage and ensuring that it remains within acceptable limits. It is a crucial component for applications where consistent and reliable operation is paramount.

With a nominal threshold voltage of 3.00V, the MCP101T-300I/TT is well-suited for 3.3V systems, providing a precise monitoring solution to protect against undervoltage conditions. Upon detecting a voltage that falls below the threshold, the device asserts a reset signal, which remains active until the voltage returns to an acceptable level, plus a certain delay time to ensure system stability. This automatic reset signal helps prevent system malfunction or data corruption that could occur due to an unexpected drop in power supply voltage.

The device comes in a compact SOT-23 package, making it ideal for space-constrained applications. It operates over an industrial temperature range of -40°C to +85°C, which ensures reliable performance even in harsh environmental conditions. Furthermore, the MCP101T-300I/TT features a low supply current of 1 µA (typical), which is advantageous for battery-operated and power-sensitive designs.

Key Features of the MCP101T-300I/TT:

• Voltage Threshold: 3.00V, suitable for 3.3V systems
• Reset Time Delay: Ensures system stability after voltage restoration
• Supply Current: Low typical current of 1 µA for power efficiency
• Operating Temperature: -40°C to +85°C for industrial applications
• Package: Small SOT-23 footprint for compact designs
• Quality: High reliability and performance characteristic of Microchip Technology products

Applications for the MCP101T-300I/TT include a wide range of electronic devices where reliable voltage monitoring is critical. These can range from consumer electronics to automotive systems, and from industrial controls to portable battery-powered devices. The integration of this supervisor IC helps to enhance the overall system robustness and can be a pivotal component in the design of a fail-safe electronic product.

By choosing the MCP101T-300I/TT, designers can ensure their systems are protected against the risks associated with undervoltage conditions, thus preserving the integrity and longevity of their electronic products.
