Maxim Integrated's MAX803TEUR+T Microprocessor Reset Circuit

The MAX803TEUR+T is a highly reliable microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. Manufactured by Maxim Integrated, this device ensures that the µP and its associated circuitry start up in the correct state every time the power is turned on and maintains that state during normal operation. The MAX803TEUR+T is particularly essential for systems where reliable operation is critical and is a vital component for maintaining system integrity during power fluctuations or failures.

This supervisory circuit provides a variety of features that make it a robust solution for system management. One of its key functionalities is the ability to assert a reset signal whenever the VCC supply voltage declines below a preset threshold, keeping the reset active for a minimum of 140ms after VCC has risen above the reset threshold. This ensures that the system has sufficient time to stabilize before the processor starts executing code.

The MAX803TEUR+T offers an active-low RESET output, which is guaranteed to be in the correct logic state for VCC down to 1.0V. This makes it suitable for use in low-voltage applications and ensures compatibility with a wide range of microprocessors and other digital systems. The device operates over a wide supply voltage range, from 1.2V to 5.5V, making it versatile for use in various applications, including portable devices, computers, embedded systems, and more.

Available in a compact SOT-23 package, the MAX803TEUR+T is designed for space-constrained applications. It is also characterized for over-temperature (up to +125°C), ensuring reliable operation in environments with varying temperature conditions. This product is provided in tape and reel form, facilitating easy integration into automated manufacturing processes.

Maxim Integrated's commitment to high-quality and reliability is evident in the MAX803TEUR+T microprocessor reset circuit, making it a preferred choice for designers looking to enhance the stability and robustness of their digital systems.
