Applications
The MCP100T-270I/TT is used in 2.7 V microcontroller and FPGA reset circuits where a hardware supervisor must assert a power-on reset and brownout reset independently of firmware. It also finds application in portable battery-powered devices, IoT sensor nodes, and industrial control modules where a tiny SOT-23 footprint is required to protect system memory or SPI flash from low-voltage corruption.

Frequently Asked Questions
At what supply voltage does MCP100T-270I/TT assert its reset output to protect a microcontroller?
The MCP100T-270I/TT trips its active-low reset output when the monitored supply drops below the 2.55 V to 2.7 V threshold window, ensuring the microcontroller is held in reset during brownout conditions to prevent corrupted firmware execution or flash write errors.
How does MCP100T-270I/TT suit a coin-cell or low-power 2.7 V IoT sensor node design?
The MCP100T-270I/TT draws very low quiescent current, making it suitable for always-on monitoring in coin-cell powered IoT nodes that operate at 2.7 V. Its 3-pin SOT-23 package adds negligible board space, so the supervisor can be placed close to the microcontroller RESET pin without impacting the PCB area budget.
What is the difference between MCP100T-270I/TT and a manually configured reset RC circuit for brownout protection?
A hardware voltage supervisor like the MCP100T-270I/TT provides a precise 2.55 V to 2.7 V trip threshold guaranteed over the −40°C to +85°C industrial temperature range, whereas an RC network has a threshold that drifts with temperature and component tolerance. The IC eliminates the component count and the calibration risk associated with passive reset circuits in production designs.
What lead time and package options should procurement engineers know when ordering MCP100T-270I/TT?
Microchip lists a factory lead time of approximately 7 weeks for MCP100T-270I/TT in the SOT-23-3 surface-mount package. The 3-lead package ships on tape-and-reel, which suits automated SMT assembly. Buyers planning high-volume production runs should verify stock with authorized distributors early, as small voltage supervisor ICs can be subject to short lead-time spikes.
