Maxim Integrated MXD1816XR29+T

The MXD1816XR29+T from Maxim Integrated is a highly reliable and precise micro-power voltage supervisor, designed to maintain system integrity by monitoring voltage levels in digital systems. This component is particularly well-suited for battery-powered devices where power efficiency is critical, as it offers a very low quiescent current, thereby helping to extend battery life.

With its compact SOT-23 package, the MXD1816XR29+T is an ideal solution for space-constrained applications. It features a factory-trimmed reset threshold voltage of 2.93V, ensuring accurate monitoring of supply voltages. In the event that the monitored voltage drops below this threshold, the device asserts a reset signal, which remains active until the voltage recovers above the threshold, plus a reset timeout period. This reset signal can be used to reboot microcontrollers or other digital logic, preventing erratic operation due to low voltage conditions.

The MXD1816XR29+T also boasts an impressive temperature range of -40°C to +125°C, making it suitable for use in harsh environments where temperature fluctuations are a concern. Its tolerance for wide temperature variations ensures that it can maintain its performance and reliability across a broad range of industrial and automotive applications.

Key features of the MXD1816XR29+T include:

• Low Quiescent Current: Ideal for battery-powered applications, it consumes minimal power to maximize battery life.
• Factory-Trimmed Reset Threshold: Provides high accuracy in voltage monitoring, with a preset threshold of 2.93V.
• Reset Timeout: After the monitored voltage returns to an acceptable level, the device keeps the reset signal active for a preset period to ensure system stability.
• Wide Operating Temperature Range: Suitable for use in a variety of environments, functioning reliably between -40°C to +125°C.
• Compact Package: The small SOT-23 footprint is perfect for space-sensitive designs.

Overall, the MXD1816XR29+T is a robust voltage supervisor that offers a blend of accuracy, reliability, and power efficiency, making it an essential component for maintaining the health and stability of electronic systems. Whether used in portable devices, automotive electronics, or industrial machinery, this device from Maxim Integrated ensures that voltage levels are appropriately supervised to prevent system failures.
