MAX16140D220JM+T

Supervisors Overview

The MAX16140D220JM+T is a nanoPower supervisor IC from Analog Devices, featuring ultra-low quiescent current of 300nA. It provides single-channel supervision with a fixed reset delay time of 100 ms and supports a maximum supply voltage of 5.5 V. The device operates within an extended temperature range of -40°C to +125°C. Packaged in a compact 4-bump wafer-level package (WLP), it integrates a manual reset input for system control. This component is designed for battery-powered applications requiring minimal power consumption while ensuring reliable voltage monitoring and reset generation.

Supervisors Feature Summary

• Ultra-low quiescent current of 300nA for extended battery life
• Single-channel supervision with fixed 100 ms reset delay
• Integrated manual reset input for system control
• Compact 4-bump WLP packaging for space-constrained designs

Supervisors Applications

• Battery-powered portable electronics
• Microcontroller system supervision
• Low-power embedded systems
• Voltage monitoring in IoT devices

Supervisors Procurement Notes

Verify the complete part number including suffixes such as +T for tape-and-reel packaging. Confirm the manufacturer is Analog Devices/Maxim Integrated. Ensure the package type matches the required 4-bump WLP configuration. Check operational temperature range specifications against application requirements. Validate that the reset delay and voltage thresholds align with system design needs before procurement.

Supervisors Selection Notes

Select this component when ultra-low standby current is critical for battery longevity. The fixed 100 ms reset delay suits applications where immediate reset is not required. The manual reset input allows for software-controlled reset functionality. Consider the 4-bump WLP package size for PCB space limitations. Ensure the 5.5 V max supply voltage covers the system's operating range.

Supervisors Part Context

The MAX16140 series includes variants like MAX16140B220KM+T and MAX16140D220LM+T, offering different package options and temperature ranges. The D220JM variant specifically denotes the 4-bump WLP package with industrial temperature rating. These supervisors are part of Maxim's nanoPower portfolio, focusing on minimal power consumption for always-on monitoring applications.

Supervisors Replacement Considerations

Direct substitutes include MAX16140B220KM+T and MAX16140D220LM+T, which share similar electrical characteristics but may differ in package or temperature range. Verify pin compatibility and functional equivalence before replacement. Cross-reference datasheets for any differences in reset delay or quiescent current specifications.
