The MAX6334UR23D3 is a precision, low-power voltage supervisor IC designed by Maxim Integrated to ensure reliable operation of microprocessor (µP) systems. This compact device monitors the power supply voltage of digital systems, providing a reset signal to the host processor whenever the monitored voltage drops below a predefined threshold, thus safeguarding against data loss and system errors during power-up, power-down, or brown-out conditions.

Key Features

• Voltage Threshold: The device is pre-set with a factory-trimmed reset threshold voltage of 2.3V, suitable for 2.5V-powered circuits, ensuring compatibility with low-voltage applications.
• Reset Timeout: After the power supply voltage returns above the reset threshold, the MAX6334UR23D3 maintains the reset output in the active state for a minimum of 140ms (typical), providing ample time for the system to stabilize.
• Low Power Consumption: With a quiescent current of only 5µA (typical), this voltage supervisor is ideal for power-sensitive applications, extending battery life in portable devices.
• High Accuracy: The device features a reset threshold accuracy of ±1.5% at room temperature, ensuring precise monitoring and reliable system operation.
• Package: The MAX6334UR23D3 comes in a compact, surface-mount SOT23-3 package, allowing for easy integration into space-constrained designs.

Applications

This voltage supervisor is particularly well-suited for use in portable/battery-powered equipment, microcontrollers, computers, controllers, and intelligent instruments where maintaining the correct operation voltage is critical. Its low power consumption and high accuracy make it an excellent choice for preserving system integrity across a range of applications.

Product Summary

The MAX6334UR23D3 from Maxim Integrated is a robust voltage supervisor IC that offers a mix of precision, low power, and small footprint, making it an essential component for ensuring the stability and reliability of microprocessor-based systems. Its ease of use and comprehensive features address the needs of a wide array of applications, from consumer electronics to industrial controls.
