The MCP103T-450E/LB is a compact, highly reliable voltage supervisor device designed and manufactured by Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This device is specifically engineered to keep microcontrollers in check by monitoring the system voltage and providing a reset signal whenever necessary, ensuring proper operation through various conditions.

Key Features

• Voltage Threshold: The MCP103T-450E/LB features a precise voltage monitoring threshold set at 4.50V, making it ideal for 5V systems that require accurate voltage supervision.
• Reset Time Delay: It includes a built-in delay timer that provides a 350 ms (typical) reset timeout period, which ensures that the system has enough time to stabilize before normal operation resumes.
• Active-Low Reset: The device offers an active-low reset output, which remains asserted until the monitored voltage rises above the specified threshold, and the delay time has elapsed, ensuring a reliable startup.
• Temperature Range: Capable of operating over an industrial temperature range from -40°C to +85°C, the MCP103T-450E/LB is suitable for harsh environments.
• Small Form Factor: It comes in a small SOT-23 package, which is ideal for space-constrained applications.
• Low Power Consumption: This voltage supervisor is designed for low power consumption, making it an energy-efficient choice for portable and battery-powered applications.
