Maxim Integrated MAX6326XR29-T Voltage Supervisor IC

The MAX6326XR29-T from Maxim Integrated is a precision, low-power microprocessor (µP) supervisory circuit designed to monitor power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with +2.5V, +3.0V, +3.3V, and +5V powered circuits.

This highly compact supervisory IC comes in a small SC70 package, which is ideal for space-constrained applications. The MAX6326XR29-T is specifically designed to maintain system integrity by monitoring the power supply voltage levels and asserting a reset signal whenever the monitored voltage drops below a factory-set threshold. The reset signal remains asserted for a minimum of 140ms after the supply voltage exceeds the reset threshold level, ensuring the system has sufficient time to stabilize.

Key features of the MAX6326XR29-T include:

• Precision Factory-Set V<sub>CC Reset Thresholds: The device comes with a preset threshold suited for a variety of applications, making it versatile for different system requirements.
• Low Power Consumption: With its low power draw, this supervisory IC is suitable for battery-operated devices, contributing to longer battery life and improved energy efficiency.
• 140ms Min Power-On Reset Pulse Width: This ensures that the µP is held in the reset state long enough to recover from power-down events or brownouts, providing a reliable system restart.
• Immune to Short V<sub>CC Transients: The MAX6326XR29-T is designed to tolerate brief voltage dips without generating false resets, enhancing system stability.
• SC70 Packaging: The small footprint of the SC70 package allows for high-density mounting and is perfect for portable applications where space is at a premium.

The MAX6326XR29-T is ideal for use in a variety of products, including computers, controllers, intelligent instruments, portable/battery-powered equipment, and other critical µP power monitoring applications. With its precision voltage monitoring and compact design, the MAX6326XR29-T is a reliable choice for designers looking to enhance the safety and robustness of their systems.
