Product Overview: MAX6389XS32D1+T from Maxim Integrated

The MAX6389XS32D1+T is a robust, precision microprocessor (μP) supervisory circuit designed by Maxim Integrated to monitor power supplies in digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used in systems with a 3.2V power supply voltage.

This supervisory circuit is specifically engineered to maintain system integrity by monitoring the power supply voltage levels. It asserts a reset signal whenever the VCC supply voltage falls below its preset threshold of 3.2V. The reset output remains asserted for a minimum timeout period after VCC has risen above the reset threshold, ensuring the system has adequate time to stabilize after a power-on or brown-out condition.

The MAX6389XS32D1+T is available in a compact, 4-pin SC70 package, making it ideal for space-constrained applications. It is characterized for operation over the extended -40°C to +125°C temperature range, catering to a wide variety of environments and use cases.
