What are the key features of MCP810T-450I/TT?
- Fixed 4.375V threshold voltage with active-high reset output for direct interface to processors and logic requiring high-asserted reset signals
- Single-channel voltage supervisor in a 3-pin SOT-23 package requiring no external components for complete reset function
- Industrial temperature range from -40°C to 125°C ensures reliable power monitoring in harsh automotive and industrial environments
- Extremely low quiescent current consumption extends battery life in always-on monitoring circuits and energy-harvesting systems
What is MCP810T-450I/TT used for?
The MCP810T-450I/TT is used as a power-on reset and undervoltage lockout supervisor in microcontroller-based systems running from a 5V supply, ensuring the processor holds reset until the supply exceeds 4.375V after power-up. It is suitable for industrial control boards, automotive ECUs, and consumer electronics where a dedicated reset IC is preferred over internal brown-out detection to achieve tighter threshold accuracy. The 3-pin SOT-23 package minimizes board space, allowing placement close to the MCU supply pin for fast transient response.

Frequently Asked Questions
At what supply voltage does MCP810T-450I/TT assert its reset output, and is the threshold adjustable?
The MCP810T-450I/TT asserts its active-high reset output when the monitored supply falls below the fixed 4.375V threshold. The threshold is not adjustable — it is laser-trimmed at manufacture. If a different threshold is needed, alternative MCP810 variants are available with threshold voltages ranging from 2.19V to 4.50V in the same 3-pin SOT-23 package.
How does the active-high reset polarity of MCP810T-450I/TT affect its use with common microcontrollers?
Most microcontrollers require an active-low reset input (RESET pin pulled low to initiate reset). The MCP810T-450I/TT active-high output is therefore suited for processors with active-high reset inputs or for driving an external inverter or MOSFET before connecting to a standard active-low MCU RESET pin. Verifying the target processor's reset polarity before selecting this device avoids a polarity mismatch.
What reset timeout period does MCP810T-450I/TT provide after the supply crosses the threshold?
The MCP810T-450I/TT asserts the reset signal while the supply is below 4.375V and releases it after the supply has remained above the threshold for a minimum internal timeout period of approximately 140 ms (typical). This delay ensures the supply voltage and oscillator have stabilized before the processor exits reset and begins executing code, preventing spurious starts during slow power-up ramps.
Which board-space-constrained designs benefit most from the 3-pin SOT-23 package of MCP810T-450I/TT?
The 3-pin SOT-23 package measures approximately 2.9 mm x 1.6 mm, making it one of the smallest available for a voltage supervisor. This footprint suits densely packed MCU boards, IoT modules, wearable electronics, and space-constrained industrial sensor PCBs where a discrete resistor-diode reset network would consume more area and offer less threshold accuracy than this single-component 4.375V supervisor.
