Microchip Technology MCP112-450E/TO Voltage Supervisor

The MCP112-450E/TO is a highly precise voltage supervisor device designed by Microchip Technology, a leader in microcontroller and analog semiconductors. This compact and efficient component is specifically crafted to maintain the reliability and stability of electronic systems by monitoring the supply voltage. It is an essential component for applications that are sensitive to voltage variations and require a dependable reset function.

Featuring a preset trigger threshold voltage of 4.5V, the MCP112 is ideal for 5V systems where it ensures that the microcontroller or processor is operating within safe voltage levels. Upon detecting a voltage drop below the threshold, the device initiates a reset signal, which remains active until the supply voltage returns to an acceptable level, plus a certain hysteresis to prevent unnecessary toggling. This reset signal is critical for preventing system crashes and data corruption that can occur during under-voltage conditions.

The MCP112-450E/TO comes in a TO-92 package, known for its through-hole mounting design, which facilitates easy integration into a variety of electronic circuits. The device is characterized for operation over a temperature range of -40°C to +85°C, making it suitable for industrial and automotive applications where temperature conditions can be extreme.

Key features of the MCP112 include:

• Accurate monitoring of 4.5V voltage threshold
• Low supply current of 1 µA (typical), which is beneficial for battery-powered applications
• High degree of temperature stability
• Immunity to short duration voltage glitches
• Built-in hysteresis to prevent false triggering

This voltage supervisor is a reliable solution for system reset in microcontrollers, intelligent instruments, portable electronics, and other applications where voltage monitoring is crucial. The MCP112-450E/TO is a testament to Microchip Technology's commitment to providing robust and high-quality components that enhance the performance and longevity of electronic systems.
