ON Semiconductor MAX810STR Microprocessor Reset Monitor

The ON Semiconductor MAX810STR is a compact, highly reliable solution designed to monitor power supplies in microprocessor systems, providing a significant layer of protection and stability. It delivers a precision monitoring function for 3V, 3.3V, and 5V supply voltages, ensuring that your microprocessor system operates within safe voltage levels. This component is essential for systems that require a dependable reset mechanism to maintain proper functioning and to protect against data corruption during power up, power down, or brown-out conditions.

With its low supply current of only 20μA (typical), the MAX810STR is an energy-efficient choice, making it suitable for battery-operated devices where power conservation is key. Its small SOT-23 package is perfect for space-constrained applications, allowing designers to maintain a compact hardware footprint without sacrificing performance or reliability.

The device features an active-low RESET output, which remains asserted for a minimum of 140ms after VCC has risen above the reset voltage threshold. This ensures a proper system reset and allows the power supply and processor to stabilize before normal operation resumes. The reset threshold accuracy is maintained over the full temperature range of -40°C to +85°C, which means the MAX810STR can be relied upon in a wide variety of environmental conditions.

For enhanced versatility, the MAX810STR includes an ability to handle a wide range of supply voltages, from 1.2V to 5.5V, providing a broad application spectrum. This component is particularly well-suited for portable devices, computers, embedded systems, and other microprocessor-based applications that require a dependable reset function.

Overall, the ON Semiconductor MAX810STR is a robust and precise solution that offers peace of mind for developers and engineers. Its combination of low power consumption, small form factor, and high reliability makes it an excellent choice for safeguarding your microprocessor systems against unpredictable power supply issues.
