- Ultra-compact SOT-23-3 package occupying minimal board space, ideal for space-constrained designs
Applications
The MCP111T-195I/TT is designed for microcontroller and microprocessor reset supervision in battery-powered portable devices, wearables, and IoT nodes operating from sub-2 V supplies. It monitors the supply rail and holds the processor in reset until the voltage exceeds the 1.95 V threshold, preventing erratic operation during power-up and brownout conditions. This device suits handheld consumer electronics, medical monitoring equipment, and industrial sensors requiring robust power sequencing.

Frequently Asked Questions
What reset threshold voltage does the MCP111T-195I/TT use, and how accurate is it?
The MCP111T-195I/TT uses a fixed 1.95 V reset threshold with ±2% accuracy. This tight tolerance ensures the open-drain RESET output reliably asserts when the supply drops below 1.95 V, providing consistent brownout protection across the full -40°C to +125°C industrial temperature range.
Which low-voltage microcontroller platforms can MCP111T-195I/TT supervise effectively?
The MCP111T-195I/TT is well suited for 1.8 V and 2.5 V microcontrollers such as low-power ARM Cortex-M0+ and MSP430 devices. Its 1.95 V trip point and open-drain output allow direct connection to processors with active-low RESET pins, and it draws only a few microamps of supply current, making it ideal for battery-powered IoT nodes operating from coin cells.
How does the SOT-23-3 package of MCP111T-195I/TT compare with larger supervisor packages for PCB layout?
The SOT-23-3 footprint measures approximately 3 mm × 1.75 mm, occupying roughly 5 mm² of board area—far less than 8-pin SOIC or MSOP alternatives. This compact size allows MCP111T-195I/TT to be placed very close to the supervised IC, minimizing trace inductance on the monitored supply rail and simplifying layout in tight handheld or wearable designs with limited PCB real estate.
