Maxim Integrated MAX6837VXSD3 Microprocessor Voltage Monitor
The MAX6837VXSD3 is a compact, low-power 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 with 3.3V-powered circuits.
This voltage monitor is specifically engineered to maintain system integrity by monitoring the power supply voltage levels and ensuring that they remain within acceptable thresholds. In the event of a power failure or a drop below a preset threshold, the MAX6837VXSD3 asserts a reset signal to the µP, effectively safeguarding the system from erratic behavior or data corruption.
Key features of the MAX6837VXSD3 include:
- Precision Monitoring: This device offers a factory-set reset threshold voltage, providing high accuracy without the need for external resistors or adjustments.
- Low Power Consumption: With a typical supply current of only 1µA, it is an ideal choice for power-sensitive applications.
- Manual Reset Input: A manual reset input is provided, allowing for a system reset to be triggered with an external switch or logic signal.
- Reset Timeout: The reset output remains asserted for a minimum timeout period after VCC has risen above the reset threshold, ensuring system stability.
- Compact Package: Offered in a small SOT-23 package, the MAX6837VXSD3 saves valuable board space in space-constrained applications.
The device is designed to be versatile, supporting a wide variety of digital systems, including portable/battery-powered equipment, computers, controllers, and intelligent instruments. Its robust feature set ensures that the MAX6837VXSD3 is an excellent choice for designers who require reliable voltage monitoring with minimal power draw.
Overall, the Maxim Integrated MAX6837VXSD3 is a testament to the company's commitment to providing innovative, high-quality integrated circuits that address the needs of modern digital systems, ensuring both efficiency and reliability.
