Applications
The MCP111-270E/TO is used to monitor supply voltages in microcontroller-based systems, ensuring a clean reset is asserted when power drops below 2.70 V during brownout or power-down events. It is commonly applied in battery-powered IoT devices, embedded controllers, and consumer electronics to prevent data corruption during voltage transients. Its open-drain output allows multiple supervisors to be wire-ORed on a shared reset line.

Frequently Asked Questions
At what voltage threshold does the MCP111-270E/TO assert its RESET output?
The MCP111-270E/TO asserts its active-low open-drain RESET output when the monitored supply voltage falls below the fixed 2.70 V threshold, providing reliable brownout detection for 3 V and 3.3 V systems with a typical accuracy of ±2%.
Can the MCP111-270E/TO be used with a 5 V microcontroller reset line?
Yes. The open-drain RESET output of the MCP111-270E/TO is compatible with 5 V logic systems when an external pull-up resistor of typically 10 kΩ is connected to the 5 V rail, allowing the device to integrate into mixed-voltage designs without level-shifting circuits.
What makes the TO-92-3 package of the MCP111-270E/TO suitable for prototyping?
The TO-92-3 through-hole package has a lead pitch of 2.54 mm, fits standard breadboards and perfboards, and simplifies hand-soldering during prototyping. It occupies less than 5 mm x 5 mm of board area, making it practical for compact supervisor circuits.
How does the MCP111-270E/TO compare to an adjustable-threshold supervisor for battery-powered designs?
For a fixed 2.70 V rail, the MCP111-270E/TO eliminates the 2 resistors required by adjustable-threshold parts, reducing BOM cost and board area by at least 2 components while maintaining ±2% threshold accuracy over -40°C to +125°C, which is sufficient for most lithium-ion discharge monitoring applications.
