Maxim Integrated MAX6310UK47D4-T Voltage Supervisor

The MAX6310UK47D4-T is a precision voltage supervisor specifically designed to maintain system integrity by monitoring the supply voltage of digital systems. Manufactured by Maxim Integrated, this compact and efficient component is vital for applications that require reliable operation under varying voltage conditions.

Encased in a small SOT-23 package, the MAX6310UK47D4-T is suitable for space-constrained applications. It features a factory-set reset threshold voltage of 4.7V, ensuring that the connected microprocessor, microcontroller, or other digital systems reset cleanly during power-up, power-down, or brown-out conditions. This predefined threshold eliminates the need for external components, simplifying the design and reducing the overall bill of materials.

The reset output of the MAX6310UK47D4-T is active-low and remains asserted for a minimum reset timeout period after VCC has risen above the reset threshold. This timeout ensures that the system has sufficient time to stabilize before the processor starts or resumes operation. The device's low supply current of typically 5µA makes it an excellent choice for portable and battery-powered equipment where power conservation is crucial.

Furthermore, the MAX6310UK47D4-T is designed to be highly reliable, with an integrated glitch immunity that prevents false resets from short-duration transients on the VCC line. This feature is essential for environments where electrical noise is present, ensuring that the system remains operational without unnecessary interruptions.

Key features of the MAX6310UK47D4-T include:

• Factory-Set Reset Threshold Voltage: 4.7V
• Low Power Consumption: 5µA (typical)
• Minimum Reset Timeout: 140ms (min)
• Operating Temperature Range: -40°C to +85°C
• Package Type: SOT-23
• Glitch Immunity to Ensure Reliable Operation

With its robust design and precise monitoring capabilities, the MAX6310UK47D4-T is an ideal solution for ensuring system stability in a wide range of applications, including computers, controllers, intelligent instruments, and portable electronics. Its integration into a system helps safeguard against data corruption and hardware damage due to undesirable voltage fluctuations.
