Product Overview: MAX809REUR-T10 from Maxim Integrated

The MAX809REUR-T10 is a precision microprocessor (μP) reset circuit developed by Maxim Integrated, a renowned leader in the design and manufacturing of analog and mixed-signal engineering solutions. This compact and efficient component is specifically designed to monitor the power supply voltage in digital systems, providing a reliable reset signal to the μP during power-up, power-down, and brown-out conditions.

The device operates by asserting a reset signal whenever the VCC supply voltage declines below a preset threshold, ensuring the μP resets properly during power failures. The reset signal remains asserted for a minimum of 140ms after VCC has risen above the reset threshold level, providing ample time for the system to stabilize.

The MAX809REUR-T10 comes in a small SOT-23 package, making it ideal for space-constrained applications. It is optimized for low power consumption and can operate with a supply voltage range from 1.2V up to 5.5V, which covers most logic levels and power supply standards used in digital systems. This feature makes it highly versatile and suitable for portable and battery-operated devices.

A notable feature of the MAX809REUR-T10 is its immunity to short-duration VCC transients, which ensures reliable operation without false triggering. This device is also characterized by its precision factory-set reset threshold voltages, which can be chosen according to the specific needs of the application.

Maxim Integrated's MAX809REUR-T10 is an essential component for system reliability and robustness, protecting microprocessors by ensuring they restart in a known state during power disturbances. Its ease of use, combined with a low component count, makes it an excellent choice for system designers looking to enhance the performance and stability of their digital systems.

Whether used in computers, controllers, intelligent instruments, or portable consumer products, the MAX809REUR-T10 is an indispensable tool for maintaining the integrity of digital systems in the face of unpredictable power supply conditions.
