Microchip Technology MCP102T-195I/TT Voltage Supervisor

The MCP102T-195I/TT is a highly reliable, compact voltage supervisor device designed by Microchip Technology, a leading provider of microcontroller, mixed-signal, analog, and Flash-IP solutions. This component is specifically engineered to keep microcontroller systems safe by monitoring the power supply voltage levels and ensuring that they remain within acceptable operating ranges.

Featuring a nominal threshold voltage of 1.95V, this voltage supervisor is perfect for low-voltage applications where precise voltage monitoring is critical. The device is housed in a small SOT-23-3 package, making it ideal for space-constrained applications. The MCP102T-195I/TT is characterized for operation over the industrial temperature range of -40°C to +85°C, ensuring reliable performance under a wide range of environmental conditions.

One of the key features of the MCP102T-195I/TT is its active-low, open-drain reset output. This feature allows it to interface directly with the reset pin of a microcontroller, providing a clear and assertive signal that the system needs to reset whenever the monitored voltage falls below the threshold. The device also has a built-in delay time which prevents it from generating false reset signals due to short duration noise or transients on the power supply line.

The MCP102T-195I/TT is designed for applications that require an efficient power-on reset control or brown-out protection, such as portable electronics, automotive systems, computers, controllers, and intelligent instruments. Its low supply current makes it an energy-efficient choice for battery-operated devices.
