Microchip Technology MCP112T-475E/TT Voltage Supervisor

The MCP112T-475E/TT is a highly reliable voltage supervisor device designed and manufactured by Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This compact component is an essential part of electronic systems where it is crucial to monitor the power supply voltage to ensure stable and proper operation of microcontrollers and other digital systems.

This voltage supervisor has a preset threshold voltage of 4.75V, making it suitable for 5V systems. When the supply voltage drops below this threshold, the MCP112T-475E/TT asserts a reset signal to the microcontroller, thus preventing any malfunction or data corruption that could occur due to an unexpected dip in the power supply. The reset signal remains active until the supply voltage returns to a safe level, ensuring the system has a chance to recover properly.

The device comes in a compact SOT-23 package, which is ideal for space-constrained applications. It is characterized for operation over a temperature range of -40°C to +85°C, making it suitable for industrial and automotive environments where temperature extremes are common. The MCP112T-475E/TT is also designed with low power consumption in mind, drawing a quiescent current of just 1 µA, thus contributing to the overall energy efficiency of the system it is monitoring.

Key features of the MCP112T-475E/TT include:

• Precision voltage monitoring for 5V systems
• 4.75V threshold voltage
• Low power consumption (1 µA typical)
• Compact SOT-23 packaging
• Wide operating temperature range (-40°C to +85°C)
• Hold-up time delay option via external capacitor

With its precision voltage monitoring and low power consumption, the MCP112T-475E/TT is a reliable choice for system designers looking to enhance the stability and robustness of their electronic products. Whether it's for consumer electronics, automotive systems, or industrial controls, this voltage supervisor from Microchip Technology provides a simple yet effective solution for power management and protection.
