MCP130T-460I/TT Microchip Integrated Circuit (SOT23 (3-Pin)) In Stock
The Microchip MCP130T-460I/TT is a single-channel voltage supervisor and reset IC with a fixed threshold of 4.35 V to 4.6 V in a miniature SOT-23-3 package. It asserts a reset signal when the monitored supply drops below the threshold, protecting microcontrollers from brownout conditions. Ideal for 5 V system supervisors in consumer electronics, industrial controllers, and embedded computing boards.

Applications
The MCP130T-460I/TT is used as a power-on reset and brownout detector for 5 V microcontroller systems in consumer appliances, industrial programmable controllers, and embedded computing boards where the processor must be held in reset until the supply rail reaches a stable 4.35 V to 4.6 V threshold. Its 3-pin SOT-23 package is a popular low-cost supervisor footprint for space-constrained designs requiring reliable power-fail detection without watchdog or programmable delay overhead.

Frequently Asked Questions
At what supply voltage threshold does MCP130T-460I/TT assert its reset output, and how does this protect a 5 V microcontroller?
The MCP130T-460I/TT monitors the supply rail and asserts the active-low RESET output when voltage falls below its fixed threshold of 4.35 V to 4.6 V. This ensures a 5 V microcontroller is held in reset during power-up ramp or supply sag events, preventing the processor from executing code from an undefined state before the supply reaches a stable 5 V operating level.
How does the fixed-threshold design of MCP130T-460I/TT compare to adjustable supervisors in terms of BOM complexity and design simplicity?
Because the MCP130T-460I/TT uses a factory-fixed threshold of 4.35 V to 4.6 V, it requires no external resistor divider network unlike adjustable supervisors. This eliminates 2 resistors from the bill of materials, reduces layout area on the PCB, and removes the design step of calculating resistor values, making it the simpler and lower-cost choice for standard 5 V microcontroller reset circuits.
Is the MCP130T-460I/TT suitable for designs requiring a watchdog timer or programmable reset delay, or should a different supervisor family be selected?
The MCP130T-460I/TT does not include a watchdog timer, manual reset input, watchdog output, or programmable reset delay, as confirmed by its feature code. Designs requiring these functions should evaluate Microchip's MCP120x or MCP130x variants with watchdog capability, or move to a higher-feature supervisor IC that adds those 4 functions while maintaining a compatible SOT-23 footprint.
What lead time should procurement plan for MCP130T-460I/TT, and does its lifecycle status support a multi-year product build?
The MCP130T-460I/TT carries a factory lead time of approximately 11 weeks, which is longer than many commodity supervisor ICs, so procurement teams should plan buffer stock for production schedules. Its YTEOL indicator of 8 years suggests continued active availability, making it a viable choice for product designs with multi-year manufacturing commitments when orders are placed with sufficient lead time through authorized Microchip distributors.
