What is MCP101-315HI/TO used for?
The MCP101-315HI/TO is commonly used in microcontroller-based embedded systems to monitor the power supply and assert a reset signal during power-up, brown-out, or power-down conditions, preventing code corruption or undefined behavior. It is well-suited for consumer electronics, industrial sensors, and IoT edge nodes that operate from regulated 3.3 V supplies and require a compact, low-power supervisory circuit. The through-hole TO-92-3 package also makes it popular in prototype boards and low-volume production where manual soldering is preferred.

Frequently Asked Questions
What is the supervisory threshold voltage of the MCP101-315HI/TO and what supply range does it support?
The MCP101-315HI/TO has a fixed supervisory threshold of 3.15 V and operates with a maximum supply voltage of 5.5 V. It draws only 45 µA of quiescent current, making it an efficient choice for always-on monitoring in battery-powered embedded systems where supply voltage fluctuations must be detected without wasting significant power.
How does the MCP101-315HI/TO help prevent microcontroller code corruption during power-supply brown-outs?
When the monitored supply voltage drops below the 3.15 V threshold, the MCP101-315HI/TO asserts a reset signal that holds the microcontroller in reset until the supply recovers. This prevents the processor from executing code at insufficient voltage levels, which could cause register corruption, flash write errors, or unpredictable firmware behavior in a single-channel reset circuit with no external components needed.
Which package does the MCP101-315HI/TO use and how does it affect PCB assembly choices?
The MCP101-315HI/TO is packaged in a 3-pin TO-92 through-hole format, which simplifies prototyping and manual assembly. Unlike surface-mount alternatives, the TO-92-3 package can be hand-soldered easily, and its 45 µA current draw means it adds negligible load to the monitored rail, making it appropriate for low-volume production runs and development boards alongside 3.3 V microcontroller designs.
When is MCP101-315HI/TO a suitable alternative to a microcontroller's built-in brown-out detection?
In designs where the microcontroller's internal brown-out detector has limited accuracy or insufficient hysteresis near the 3.15 V threshold, the MCP101-315HI/TO provides a dedicated, calibrated external supervisor that reliably holds reset for supply excursions. It is particularly valuable in systems with noisy power rails up to 5.5 V maximum where the on-chip BOD may generate spurious resets, and it costs minimal board space in the compact TO-92-3 footprint.
