MXD1813XR44+T

Supervisors Overview

The MXD1813XR44+T is a single-channel voltage supervisor from the Maxim Integrated portfolio, housed in a compact SC-70-3 surface-mount package. It operates within a supply voltage range of 1.2 V to 5.5 V and features a fixed threshold voltage of 4.4 V for monitoring power rails. The device draws only 9 µA of quiescent current, ensuring minimal impact on battery life in portable applications. It provides an active-high, push-pull output with a standard reset delay time of 250 ms. Designed for industrial environments, it functions reliably across a temperature range of -40°C to +105°C.

Supervisors Feature Summary

• Ultra-low power consumption suitable for battery-operated systems
• Compact SC-70-3 footprint for space-constrained designs
• Active-high push-pull output driver for direct logic interfacing
• Fixed threshold voltage for simplified circuit implementation

Supervisors Applications

• Portable electronic devices requiring efficient power management
• Industrial control systems operating in harsh thermal environments
• Battery-powered instrumentation and sensor nodes
• Embedded microcontroller system supervision

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and specific manufacturing date codes against project requirements. Ensure proper handling procedures are followed during storage and assembly to maintain device integrity. Cross-reference ordering information with official datasheets to avoid specification mismatches.

Supervisors Selection Notes

Select this component when a fixed 4.4 V threshold is required for system supervision. Consider the active-high output polarity and 250 ms delay characteristics against target logic timing requirements. Evaluate the SC-70-3 package dimensions against available board real estate. Compare quiescent current specifications with alternative supervisors if extended battery life is critical.

Supervisors Part Context
