Maxim Integrated MAX6831SVUT+T Voltage Supervisor IC

The MAX6831SVUT+T from Maxim Integrated is a highly reliable, 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 5V-powered circuits.

This voltage supervisor IC ensures that your system's microprocessor is reset to a known state during power-up, power-down, or brown-out conditions. The MAX6831SVUT+T features a preset voltage threshold of 4.63V, which is suitable for monitoring 5V power supplies. When the monitored voltage falls below this threshold, the reset output is asserted, which remains active for a minimum of 140ms after the supply voltage rises above the reset threshold. This delay ensures the system has sufficient time to stabilize before the processor starts executing code.

Designed with versatility in mind, the MAX6831SVUT+T is available in a small, 6-pin SOT-23 package, making it ideal for space-constrained applications. It is also specified over the extended temperature range of -40°C to +85°C, ensuring reliable operation under varying environmental conditions.

Key features of the MAX6831SVUT+T include:

• Factory-trimmed V<sub>CC reset threshold for 5V systems.
• Low, 1.6µA supply current makes it ideal for portable equipment.
• Manual reset capability with a debounced input.
• 140ms min reset timeout delay.
• Immune to short V<sub>CC transients.
• Available in a small 6-pin SOT-23 package.

The MAX6831SVUT+T is targeted for a wide range of applications, including computers, controllers, intelligent instruments, portable/battery-powered equipment, and embedded systems. Its simplicity of use, combined with its small footprint and low power consumption, makes it an excellent choice for maintaining system integrity and preventing data corruption during power instability.

By integrating the MAX6831SVUT+T into your design, you can significantly enhance system reliability and performance, ensuring that your products meet the highest standards of quality and robustness expected in today's competitive market.
