The Maxim Integrated MAX6423XS29+T 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 in systems with a 2.9V power supply voltage.
This device is adept at providing a precise, factory-trimmed reset threshold suitable for operation with a variety of microprocessors, including low-voltage, low-power varieties. It asserts a reset signal whenever the VCC supply voltage declines below the preset threshold, ensuring that the µP resets cleanly during power-up, power-down, and brown-out conditions.
The MAX6423XS29+T comes in a compact, 4-pin SC70 package, making it an ideal choice for space-constrained applications. Its small size, combined with its SOT (small outline transistor) packaging, allows for efficient use of board space without sacrificing performance.
One of the key features of this reset circuit is its low supply current, which is typically only 1µA, making it suitable for portable and battery-operated applications. It also has a reset timeout period of 140ms (min), ensuring that the system has sufficient time to stabilize before coming out of reset.
The MAX6423XS29+T operates over a wide temperature range of -40°C to +125°C, which makes it reliable in extreme environmental conditions. Additionally, it is offered in a lead(Pb)-free, RoHS-compliant package, adhering to current environmental standards for electronic components.
In summary, Maxim Integrated's MAX6423XS29+T is a versatile, easy-to-use, and efficient solution for microprocessor reset applications. Its precise voltage monitoring capability, low power consumption, and small footprint make it an excellent choice for maintaining system integrity across a variety of digital applications.
