Microchip Technology MCP810T-450I/TT Voltage Supervisor

The MCP810T-450I/TT is a highly reliable voltage supervisor device designed by Microchip Technology, a leader in smart, connected, and secure embedded control solutions. This compact component is crucial for various applications where it is essential to monitor the voltage levels in digital systems, ensuring proper operation and providing a safeguard against undesirable system resets.

With its precision voltage monitoring capability, the MCP810T-450I/TT is tailored to maintain system integrity by monitoring the supply voltage. It offers a nominal threshold voltage of 4.50V, which makes it suitable for 5V systems. Upon detecting a voltage drop below the threshold, it asserts a reset signal, which remains active until the system voltage stabilizes above the minimum threshold for a specific period, known as the reset timeout period.

This voltage supervisor comes in a tiny three-pin SOT-23 package, which is ideal for space-constrained applications. Its industrial temperature range of -40°C to +85°C ensures reliable operation in harsh environments, making it a versatile choice for industrial, automotive, and consumer electronics.

Key features of the MCP810T-450I/TT include:

• Threshold Voltage: Precisely set at 4.50V for monitoring 5V power supplies.
• Reset Timeout: 350 ms minimum reset timeout period provides system stability.
• Output Type: Active-low, open-drain output which requires minimal external components for interfacing.
• Low Power Consumption: Designed for energy-efficient operation, reducing the overall power demand of the system.
• Package: Available in a small SOT-23 package, suitable for compact PCB layouts.
• Temperature Range: Operates reliably over an industrial temperature range.

The MCP810T-450I/TT is an essential component for designers looking to enhance system reliability and protect against potential damage caused by unexpected undervoltage conditions. Its simplicity, combined with Microchip's reputation for quality, makes it a trusted and economical choice for voltage monitoring applications.
