Maxim Integrated MAX6351LSUT+T Voltage Reference

The MAX6351LSUT+T from Maxim Integrated is a precision, low-noise, low-drift microprocessor (μP) reset circuit that provides an accurate voltage reference and a watchdog timer. Designed for high-reliability applications that require long-term stability and precision, this device is well-suited for a wide range of products including industrial controls, portable devices, and sophisticated electronics where a stable reference voltage is crucial.

With a typical output voltage of 3.0V, the MAX6351LSUT+T offers an impressive initial accuracy of ±1%. It maintains this accuracy over a temperature range of -40°C to +125°C, ensuring reliable performance in diverse operating conditions. The low temperature coefficient of typically 20ppm/°C further enhances its stability, making it an excellent choice for applications that demand a consistent voltage reference regardless of temperature fluctuations.

The device features a low supply current of typically 5.5μA, which is particularly beneficial for battery-powered devices where power efficiency is paramount. Additionally, the MAX6351LSUT+T includes a reset output that remains asserted for a minimum of 140ms after VCC has risen above the reset threshold, providing ample time for the μP and other circuits to stabilize.

One of the standout features of the MAX6351LSUT+T is its integrated watchdog timer. This safety mechanism ensures that if a system becomes unresponsive or fails to toggle the watchdog input within a preset timeout period, the device will generate a system reset. This feature is invaluable for maintaining system integrity and preventing failures in critical applications.

The MAX6351LSUT+T comes in a compact SOT-23 package, making it an excellent choice for space-constrained designs. Its surface-mount form factor allows for efficient assembly and integration into printed circuit boards (PCBs).

Overall, the Maxim Integrated MAX6351LSUT+T voltage reference is a high-quality, reliable component that offers the precision and stability needed for demanding applications. Its low power consumption, integrated watchdog timer, and compact size make it a versatile choice for designers looking to enhance the performance and reliability of their electronic systems.
