Maxim Integrated MAX6389XS31D1/V+T Voltage Supervisor IC

The MAX6389XS31D1/V+T from Maxim Integrated is a high-quality voltage supervisor integrated circuit (IC) designed to ensure reliable operation of microprocessors (µPs), microcontrollers (MCUs), and other digital systems. This precision device monitors the power supply voltage of digital systems, asserting a reset signal whenever the monitored voltage drops below a preset threshold, thereby safeguarding the system from erratic behavior that can occur during power-up, power-down, or if a power failure occurs.

With a factory-set threshold voltage of 3.1 volts, the MAX6389XS31D1/V+T is well-suited for applications that operate within the common 3.3V power supply range. It offers an active-low, open-drain reset output, which remains asserted for a minimum reset timeout period after the supply voltage rises above the reset threshold. This ensures that the system has adequate time to stabilize before the processor begins operation.

Key features of the MAX6389XS31D1/V+T include:

• High Accuracy: This device provides a tight threshold voltage accuracy, which is essential for systems that cannot tolerate wide voltage variations.
• Low Power Consumption: Designed for power-sensitive applications, it operates with minimal power consumption, thus preserving battery life in portable devices.
• Immune to Short V_CC Transients: The IC is built to ignore brief dips in the power supply, thereby avoiding unnecessary resets due to transient conditions.
• Compact Form Factor: Available in a small, surface-mount SOT-343 package, the MAX6389XS31D1/V+T is ideal for space-constrained applications.
• Extended Temperature Range: This device is specified over an extended industrial temperature range, making it suitable for harsh environments.

Applications for the MAX6389XS31D1/V+T are diverse, ranging from portable electronics and handheld devices to industrial controllers and automotive systems where consistent and reliable operation is critical. By integrating this voltage supervisor into your design, you can enhance system reliability and protect against the potential risks associated with unexpected power supply variations.

Maxim Integrated's commitment to quality ensures that the MAX6389XS31D1/V+T voltage supervisor IC is a dependable choice for maintaining the integrity of your digital systems.
