The MAX6328XR29+T from Maxim Integrated is a precision, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in digital systems. It provides a significant level of system reliability through its ability to assert a reset signal whenever the VCC supply voltage drops below a preset threshold, ensuring that the µP and its peripherals are reset properly during power-up, power-down, or brown-out conditions.

Key Features

• Precision Factory-Set V<sub>CC Reset Thresholds: The device comes with a factory-set reset threshold voltage of 2.93V, tailored for 3V-powered systems, ensuring accurate monitoring without the need for external components.
• Low Power Consumption: Designed for battery-operated and portable applications, the MAX6328XR29+T consumes minimal power, with a typical supply current of only 1µA, contributing to extended battery life.
• Low Dropout Voltage: The device operates effectively even with very low voltage differences between the input and output, making it suitable for low-voltage environments.
• Guaranteed Reset Valid to V<sub>CC = 1V: Reliable operation is ensured with guaranteed reset output from V<sub>CC = 1V, providing system stability across a wide range of operating conditions.
• Immune to Short V<sub>CC Transients: Fast transients on the V<sub>CC line are filtered, preventing unnecessary resets and enhancing system robustness.

Applications

The MAX6328XR29+T is ideal for use in a variety of applications where accurate voltage monitoring and system reliability are paramount. These include:

• Computers and Controllers
