Applications
The MCP120-475I/SN is used in microcontroller and microprocessor reset circuits where a 4.75 V supply rail must be monitored to prevent erratic operation during power-up or brownout events. It suits industrial control boards, embedded systems, and consumer electronics requiring a simple, low-component-count supervisor with an open-drain reset line that can be wire-OR'd with other reset sources.

Frequently Asked Questions
What supply voltage threshold does the MCP120-475I/SN monitor, and how does it assert its reset output?
The MCP120-475I/SN monitors a 4.75 V fixed threshold on the monitored supply rail. When the supply drops below this 4.75 V level, the open-drain, active-low reset pin is asserted low, holding the connected microcontroller or processor in reset to prevent erratic operation during brownout or power-up transients. The open-drain topology allows the reset line to be wire-OR'd with other reset sources in multi-supervisor systems.
Which embedded system designs benefit most from the MCP120-475I/SN 4.75 V supervisor in an SOIC-8 package?
Embedded systems powered from a regulated 5 V rail — such as industrial PLCs, motor-control boards, and data-acquisition units — benefit most from this part. The SOIC-8 footprint occupies roughly 5 mm × 4 mm of PCB area, making it easy to place near the microcontroller it protects. The single-channel architecture keeps BOM cost low while ensuring the processor receives a clean reset signal whenever the 5 V supply dips below 4.75 V.
How does MCP120-475I/SN compare to adjustable-threshold supervisors when a 4.75 V trip point is required?
Unlike adjustable-threshold supervisors that require 2 external resistors to set the trip point — typically adding ±1% to ±2% tolerance on top of the resistor tolerances — the MCP120-475I/SN uses an internal precision reference calibrated to 4.75 V, eliminating the external divider and reducing component count by at least 2 passives. This lowers assembly cost and board space while providing a factory-trimmed threshold accuracy suitable for most 5 V microcontroller applications.
Is the MCP120-475I/SN RoHS compliant, and what is the typical lead time for procurement?
Yes, the MCP120-475I/SN carries a Pb-free (RoHS-compliant) designation per its JESD-609 Code e3 marking. The factory lead time is approximately 6 weeks for direct orders, though authorized distributors typically maintain stock for immediate shipment. The part ships worldwide and is available in standard SOIC-8 tape-and-reel packaging.
