Key Features
- Fixed 1.95 V threshold detection with micropower quiescent current for battery-sensitive designs
- Single-channel open-drain reset output in a compact 3-pin TO-92 package for easy PCB integration
- Industrial temperature range operation suitable for -40°C to +125°C environmental conditions
Applications
MCP111-195I/TO monitors supply voltages in microcontroller-based systems, asserting a reset output when the supply falls below 1.95 V to prevent erratic processor operation during power-up or brownout conditions. Its micropower consumption makes it ideal for coin-cell and low-power IoT sensor nodes where every microamp of standby current matters. The TO-92 through-hole package simplifies installation in prototyping boards, legacy industrial control panels, and cost-sensitive consumer electronics where SMD assembly is not available.

Frequently Asked Questions
At what supply voltage does MCP111-195I/TO assert its reset output, and how does the threshold behave over temperature?
MCP111-195I/TO asserts its active-low reset output when the monitored supply drops below the fixed 1.95 V threshold. Microchip specifies a tight threshold accuracy of typically ±2% across the -40°C to +125°C industrial range, so the reset trips between 1.91 V and 1.99 V worst-case. This precision ensures reliable brownout detection for 2.0 V logic rails in IoT and embedded systems without requiring external voltage reference trimming.
How does MCP111-195I/TO's TO-92 package simplify integration compared to surface-mount voltage detectors?
The 3-pin TO-92 package has 2.54 mm through-hole pitch, compatible with standard breadboards and single-sided PCBs. Unlike SOT-23 SMD supervisors that require reflow soldering and careful pad alignment, the TO-92 can be hand-soldered or socketed in 5 minutes with basic tools. Lead length of approximately 12 mm also allows mounting above a PCB surface in prototype rigs, making MCP111-195I/TO the preferred choice for university labs and field-repair scenarios.
When should a designer choose MCP111-195I/TO over an adjustable threshold supervisor for a 2.0 V rail?
For a fixed 2.0 V supply rail, MCP111-195I/TO's 1.95 V factory-calibrated threshold eliminates the 2 external resistors and associated tolerance stack-up that an adjustable supervisor requires. With resistor values at 1% tolerance, an adjustable supervisor's effective threshold varies by ±2% to ±3% including reference error, whereas MCP111-195I/TO delivers ±2% accuracy from a single component. This saves 2 BOM items, reduces 10 mm² of PCB area, and cuts supply chain complexity for high-volume production.
