What are the key features of MCP130-475FI/TO?
- Single-channel voltage supervisor with factory-set 4.75 V reset threshold monitors VCC and asserts reset with no external components required
- Internal 5 kOhm pull-up resistor on open-drain reset output eliminates the need for an external pull-up in 5 V microcontroller designs
- TO-92-3 through-hole package with 3-lead footprint fits standard DIP PCB layouts and breadboards for easy prototyping and low-cost production
What is MCP130-475FI/TO used for?
The MCP130-475FI/TO is used in 5 V microcontroller systems, industrial PLCs, and embedded control boards to guarantee a valid reset pulse whenever the supply drops below 4.75 V during power-on, brownout, or momentary interruptions. Its fixed threshold eliminates calibration and external resistor dividers, making it a zero-BOM-overhead addition to any 5 V MCU design. Consumer electronics, point-of-sale terminals, and alarm control panels use it to prevent data corruption and undefined states during unstable supply transitions.

Frequently Asked Questions
At what supply voltage does MCP130-475FI/TO assert its reset output, and how long does it hold reset after VCC recovers?
The MCP130-475FI/TO asserts the active-low reset output when VCC falls below the 4.75 V trip threshold. After VCC rises back above this threshold, the device holds reset asserted for a minimum reset timeout period of approximately 140 ms, giving the MCU oscillator and power rails time to fully stabilize before releasing the reset line and allowing program execution to begin.
Does MCP130-475FI/TO include a built-in pull-up on its reset pin, and what value is it?
Yes. The MCP130-475FI/TO integrates a 5 kOhm pull-up resistor on the open-drain reset output, pulling the line to VCC when reset is deasserted. This eliminates the need for an external resistor in standard 5 V MCU designs, reducing component count by 1 passive and simplifying the schematic. In designs where a different pull-up impedance is needed, an external resistor can be added in parallel.
How does MCP130-475FI/TO differ from the MCP130-300 variant, and which system voltage does each target?
The MCP130-475FI/TO has a factory-set trip threshold of 4.75 V, making it suitable for 5 V supply rails where brownout detection should trigger before VCC drops below the 4.5 V minimum operating limit of most 5 V MCUs. The MCP130-300 variant has a 3.00 V trip threshold and targets 3.3 V systems. Both share the same TO-92-3 package and internal 5 kOhm pull-up, so they are pin-compatible and interchangeable on the same PCB layout.
