What are the key features of MCP100-475HI/TO?
- Fixed 4.75 V reset threshold with active-low open-drain output for direct MCU RESET line connection
- Single-channel voltage supervisor requiring no external components for threshold setting
- TO-92-3 through-hole package ideal for prototyping and through-hole industrial assemblies
- Non-adjustable threshold for consistent reset behavior across production units
- RoHS-compliant lead-free construction (JESD-609 Code e3)
- Wide temperature tolerance suitable for industrial temperature ranges
What is MCP100-475HI/TO used for?
MCP100-475HI/TO is used in microprocessor and microcontroller power supervision circuits to generate a clean reset signal during power-up and brownout conditions in industrial control panels, embedded systems, and consumer electronics. It is particularly useful in 5 V logic systems where the fixed 4.75 V threshold matches standard supply tolerances. Designers use it in alarm panels, programmable logic controllers, and data logging equipment to prevent corrupt firmware execution during low-voltage events.

Frequently Asked Questions
At what voltage threshold does MCP100-475HI/TO assert its reset output, and is the threshold adjustable?
MCP100-475HI/TO asserts its active-low reset output when VCC falls below the fixed 4.75 V threshold. The threshold is not adjustable, which simplifies design by eliminating external resistor dividers and ensures consistent reset behavior across all production units operating on a 5 V supply rail.
How does the active-low open-drain output of MCP100-475HI/TO interface with a microcontroller RESET pin?
The open-drain active-low output can be connected directly to a microcontroller RESET pin with a pull-up resistor to VCC. When VCC drops below 4.75 V, the output is pulled low, asserting the reset. When voltage recovers, the output is released high, allowing the MCU to begin normal operation after the internal reset delay.
What package does MCP100-475HI/TO use, and in which assembly processes is it practical?
MCP100-475HI/TO comes in a TO-92-3 through-hole package, which is suitable for hand soldering, prototyping, and low-volume through-hole PCB assembly. The 3-pin through-hole format is compatible with standard DIP-socket-style layouts and is easy to replace during field servicing of industrial equipment.
What is the lead time for MCP100-475HI/TO, and what alternatives exist if a fixed 4.75 V threshold does not match my supply?
MCP100-475HI/TO has a factory lead time of approximately 10 weeks from Microchip. If a different fixed threshold is required, Microchip's MCP100 series offers variants with thresholds such as 4.38 V, 4.63 V, and 3.08 V for 3.3 V systems. Engineers should verify the threshold suffix in the MPN when selecting a replacement to match their supply voltage tolerance.
