Applications
The MCP112T-240E/TT is used to monitor supply rails in battery-powered microcontroller systems, generating a reset signal when the supply drops below the 2.32V threshold during brownout or battery drain events. It is commonly found in wireless sensor nodes, portable consumer electronics, and IoT edge devices that operate from lithium or alkaline cells where reliable power-on reset behavior is critical.

Frequently Asked Questions
At what supply voltage does the MCP112T-240E/TT assert its reset output to protect a microcontroller?
The MCP112T-240E/TT asserts its active-low reset output when the monitored supply voltage falls below the 2.32V detection threshold (specified between 2.262V and 2.378V). This threshold is factory-trimmed, requiring no external resistor divider and providing a stable brownout detection point for 2.5V-powered MCU systems.
Does the MCP112T-240E/TT include a watchdog timer or only perform voltage supervision?
The MCP112T-240E/TT is a pure voltage detector with no watchdog timer, no programmable reset delay, and no manual reset input. It performs only a single function: monitoring the supply rail and asserting an open-drain reset signal whenever the voltage drops below the 2.32V trip point, keeping the device cost and current consumption minimal.
How does the SOT-23-3 package size of the MCP112T-240E/TT benefit space-constrained wearable designs?
The SOT-23-3 package measures approximately 1.75 mm x 2.9 mm with a 0.95 mm pin pitch, making it one of the smallest available supervisor housings. In wearable devices and compact IoT modules where every square millimeter of board space matters, this 3-pin leadframe reduces the supervisor footprint to a fraction of larger 8-pin options.
What is the quiescent current consumption of the MCP112T-240E/TT for battery life estimation?
The MCP112T-240E/TT typically draws less than 50 µA of quiescent current from the monitored supply rail. For a 250 mAh coin-cell battery used in an IoT sensor, the supervisor alone would contribute only about 5,000 hours of drain at nominal voltage, making its power impact negligible compared to the MCU and radio subsystems.
