Maxim Integrated DS1831CS+ Product Overview
The DS1831CS+ is a robust, high-precision microprocessor supervisory circuit designed by Maxim Integrated, a leader in the development of innovative analog and mixed-signal products. This device is engineered to monitor the power supply and temperature of microprocessor (µP) systems, ensuring reliable operation and preventing data corruption due to unexpected power failures or abnormal system conditions.
Featuring a compact SOP-8 package, the DS1831CS+ is ideal for space-constrained applications where board real estate is at a premium. It provides a precise, factory-trimmed V<sub>CC reset threshold and has an active-low RESET output that remains asserted until the V<sub>CC has stabilized after turning on and during a brownout condition. This ensures the µP boots up safely every time power is applied or restored.
The DS1831CS+ includes an additional feature, an active-high RESET output, which complements the active-low RESET by providing a different reset signal polarity if required by specific system designs. Both RESET outputs are guaranteed to be in the correct state for V<sub>CC down to 1.2V, allowing for reliable performance even during low voltage conditions.
Another key feature of the DS1831CS+ is its watchdog timer, which helps to prevent system failure by resetting the µP if it fails to strobe within a preset timeout period. This is crucial for applications that cannot tolerate system hang-ups and require continuous monitoring to ensure proper operation.
The DS1831CS+ also boasts a high-temperature operation range of -40°C to +85°C, making it suitable for use in harsh environments where temperature extremes are common. Its low power consumption makes it an excellent choice for battery-powered devices, contributing to extended operational life and reliability.
Overall, the DS1831CS+ from Maxim Integrated is a versatile and reliable solution for system monitoring, providing essential protection against power and temperature anomalies in a wide range of µP-based applications. With its compact size, precision features, and robust design, it is an ideal choice for designers looking to enhance system stability and integrity.
