Frequently Asked Questions
At what threshold voltage does MCP101-450DI/TO assert a reset to protect downstream microcontrollers?
MCP101-450DI/TO has a fixed reset threshold of 4.50 V. When the monitored supply drops below this level, the device asserts an active-low RESET output, holding the microcontroller in reset until the supply recovers and a minimum timeout delay expires, preventing code corruption during power interruptions.
How does MCP101-450DI/TO simplify brownout protection design compared to a discrete resistor-divider comparator approach?
MCP101-450DI/TO is a factory-trimmed voltage supervisor with an accurate 4.50 V threshold and integrated reset timeout, eliminating the need for an external comparator, precision resistors, and filter capacitors. A single TO-92-3 IC replaces 4 to 6 discrete components, reducing BOM count and PCB area while improving threshold accuracy to within a few millivolts.
What is the lead time for MCP101-450DI/TO and how should procurement teams plan for it?
MCP101-450DI/TO has a factory lead time of 15 weeks from Microchip, which is longer than many standard logic ICs. Procurement teams designing for volume production should carry 3 to 6 months of safety stock or qualify an alternate supervisor IC with a compatible 4.5 V threshold and TO-92 or SOT-23-3 footprint.
Is MCP101-450DI/TO suitable for use in industrial equipment operating over a wide temperature range?
MCP101-450DI/TO in the DI temperature grade supports an industrial operating temperature range of -40°C to +85°C, making it appropriate for factory automation, HVAC control panels, and outdoor embedded systems exposed to seasonal temperature extremes without additional thermal management.
