Key Features
- 3.00 V precision voltage threshold triggers open-drain RESET output protecting microcontroller power-on integrity
- Minimum 140 ms reset timeout delay ensures stable power rails before the RESET line is released
- Compact 3-pin SOT-23 package with -40°C to +85°C industrial temperature range for harsh-environment deployments
Applications
The MCP130T-300I/TT is ideal for supervising power supplies of microcontrollers and microprocessors in embedded systems, asserting a clean RESET when VCC drops below 3.00 V. It is widely used in battery-powered IoT devices, handheld instruments, and industrial control units where reliable power-on reset and brown-out detection are critical. Its 3-pin SOT-23 footprint enables easy integration into space-constrained PCB layouts.

Frequently Asked Questions
At what supply voltage does the MCP130T-300I/TT assert its RESET signal?
The MCP130T-300I/TT asserts its open-drain RESET output when VCC drops below the 3.00 V threshold. It releases RESET only after VCC rises back above 3.00 V and a minimum timeout delay of 140 ms has elapsed, ensuring a fully stable supply before the microcontroller begins execution.
How long is the reset timeout delay on the MCP130T-300I/TT and why is it important?
The MCP130T-300I/TT provides a minimum reset timeout of 140 ms after VCC exceeds the 3.00 V trip point. This interval allows bulk capacitors to fully charge and clock oscillators to stabilize, preventing spurious resets in 3.3 V microcontroller systems during power-up or after a brown-out event.
For which temperature environments is the MCP130T-300I/TT qualified, and what package does it ship in?
The MCP130T-300I/TT carries an industrial temperature rating of -40°C to +85°C and is housed in a 3-pin SOT-23 package. This makes it appropriate for factory automation controllers, outdoor IoT sensor nodes, and automotive accessory boards where both compact size and wide thermal tolerance are required.
