Microchip Technology's MCP112T-300E/LB Voltage Supervisor IC

The MCP112T-300E/LB is a compact, highly reliable voltage supervisor device designed by Microchip Technology, a leading provider of smart, connected, and secure embedded control solutions. This device is specifically engineered to keep microcontroller-based systems safe by monitoring the power supply voltage and ensuring that it remains within acceptable limits.

This voltage supervisor IC operates over a voltage range of 1.0V to 5.5V, making it suitable for low-voltage applications, including battery-operated devices. The MCP112T-300E/LB is particularly notable for its preset trigger threshold voltage of 3.00V, which is the point at which the device will assert a reset signal if the monitored voltage falls below this value. This feature is crucial for preventing microprocessor lock-up, ensuring reliable operation, and providing a robust defense against power supply glitches and brownouts.

The device comes in a 3-pin TO-92 package, which is widely used in the industry and known for its ease of integration into various circuit designs. The MCP112T-300E/LB is characterized by its low power consumption, making it an energy-efficient choice for portable and battery-powered applications. Its active-low, open-drain reset output allows it to interface directly with the reset pin of a microcontroller, providing a simple and effective way to manage system resets.

Additional features include a built-in delay on the output, which prevents nuisance resets by ensuring that the device only asserts the reset signal if the under-voltage condition persists for a specified period. This delay is factory-set, eliminating the need for external components and simplifying the design process.

With its combination of low power consumption, precision voltage monitoring, and easy integration, the MCP112T-300E/LB is an excellent choice for designers looking to enhance the reliability and performance of their systems. Whether it's used in consumer electronics, automotive applications, or industrial controls, this voltage supervisor IC from Microchip Technology helps to maintain system integrity and protect against the consequences of undesirable voltage drops.
