Key Features
- Fixed 4.375 V threshold voltage supervisor with active-high reset output for reliable microcontroller power-on reset in 5 V systems
- Ultra-compact 3-pin SOT-23 (SOT-23-3) package occupying less than 2 mm x 2 mm of PCB area for space-constrained designs
- Single-function reset IC with no external components required, simplifying BOM and reducing system cost in embedded power management circuits
Applications
MCP101T-450I/TT is designed for microcontroller and processor reset circuits in 5 V embedded systems, industrial controllers, and consumer electronics requiring reliable power-on and brownout reset supervision. Its fixed 4.375 V threshold generates an active-high reset signal whenever the supply voltage drops below the set level, ensuring controlled processor restart. The 3-pin SOT-23 package makes it easy to populate on any PCB requiring a dedicated supervisor adjacent to the microcontroller supply pin.

Frequently Asked Questions
At what voltage level does MCP101T-450I/TT assert its reset output signal?
MCP101T-450I/TT asserts its active-high reset output when the monitored supply voltage falls below the fixed 4.375 V threshold. This ensures the connected microcontroller or processor is held in reset during brownout conditions, preventing erratic operation caused by insufficient supply voltage in 5 V embedded systems.
How does the 3-pin SOT-23 package of MCP101T-450I/TT benefit compact embedded board layouts?
The 3-pin SOT-23 package measures approximately 1.5 mm x 2.9 mm, making MCP101T-450I/TT one of the smallest possible supervisor footprints available. This compact size allows placement directly adjacent to the microcontroller VCC pin on densely populated PCBs such as IoT sensor nodes and portable instrument boards.
Is MCP101T-450I/TT adjustable, and what supply monitoring scenario is it best suited for?
MCP101T-450I/TT has a fixed, non-adjustable threshold of 4.375 V, making it best suited for 5 V power rails where a brownout threshold near 4.375 V is acceptable. Unlike adjustable supervisors requiring external resistors, the fixed threshold simplifies design and eliminates resistor tolerance errors in applications such as 5 V microcontroller boards and industrial PLC I/O modules.
