Frequently Asked Questions
At what supply voltage does MCP100-300DI/TO assert its reset output to protect a 3.3 V microcontroller?
MCP100-300DI/TO asserts the active-low RESET output when the monitored supply drops below the fixed 3.0 V trip threshold, keeping a 3.3 V microcontroller held in reset until the supply recovers and stabilizes above that level.
Does MCP100-300DI/TO require external resistors or capacitors to function as a power-on reset circuit?
No external components are required for the basic reset function. MCP100-300DI/TO integrates the trip threshold and reset timing internally, which simplifies PCB layout and reduces BOM cost for single-channel voltage supervisory needs.
Why might a designer choose the TO-92-3 package of MCP100-300DI/TO over an SOT-23 alternative?
The 3-pin TO-92 package allows hand soldering and socket insertion, which is preferred for through-hole prototype boards, low-volume builds, and field-replaceable assemblies where surface-mount rework tooling is not available.
How does MCP100-300DI/TO compare to a software reset routine for protecting firmware against brown-out events?
Hardware supervisors like MCP100-300DI/TO assert the RESET line before the supply drops to a level where firmware execution becomes unreliable, typically acting within microseconds of a 3.0 V threshold crossing without relying on software, which cannot run correctly during severe brown-out conditions.
