Maxim Integrated MAX6316LUK31CY+T Microprocessor Reset Circuits

The MAX6316LUK31CY+T is a highly reliable 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 3.1V-powered circuits. This component from Maxim Integrated ensures that the µP is reset to a known state during power-up, power-down, or brown-out conditions.

The MAX6316 series comes in a compact SOT-23 package, making it ideal for space-constrained applications. The MAX6316LUK31CY+T variant features an active-low, push-pull reset output. The reset signal is guaranteed to remain asserted for a minimum of 140ms after VCC has risen above the reset voltage threshold, providing ample time for the system to stabilize.

One of the key features of this device is its ability to provide a precise voltage monitoring option. With a factory-set reset threshold voltage of 3.1V, it is tailored for applications that operate around this voltage level. Additionally, the component has a low supply current of only 1.5µA (typical), which is particularly beneficial for battery-powered devices where power efficiency is crucial.

The MAX6316LUK31CY+T is equipped with a debounce feature that filters out fast transients on VCC. This ensures that the reset output will only be issued during genuine power failures or dips below the threshold voltage, preventing unnecessary system resets due to noise or brief voltage fluctuations.

Maxim Integrated's commitment to quality and reliability is evident in this product, which is designed to operate over a wide temperature range of -40°C to +85°C. This makes it suitable for use in a variety of environments, from industrial to commercial applications. The device's lead-free composition and RoHS compliance also make it an environmentally friendly choice for modern electronic designs.
