MAX16039LLA26/GG8

Supervisors Overview

The MAX16039LLA26/GG8 is a low-power voltage supervisory circuit designed for battery backup applications. It features a threshold voltage of 2.63 V and operates within a supply voltage range up to 5.5 V. The device provides an active-low, open-drain output with a reset delay time of 140 ms minimum. It consumes only 22 uA of operating current and functions reliably across a temperature range from -40 C to +85 C. Packaged in an 8-µDFN (2x2) format, it supports single-input monitoring without manual reset or watchdog timer capabilities.

Supervisors Feature Summary

• Integrates battery backup switching functionality within a compact surface-mount package
• Provides precise voltage supervision with defined threshold detection levels
• Delivers active-low open-drain status output for system integration

Supervisors Applications

• Battery backup circuit implementation
• Voltage monitoring in portable electronics
• System reset generation for microcontrollers

Supervisors Procurement Notes

Verify component authenticity through authorized Analog Devices channels due to discontinuation status at major distributors. Confirm package marking and lot traceability against official datasheet specifications. Ensure storage conditions comply with moisture sensitivity levels for the UDFN-8 package. Validate electrical parameters against the specific suffix requirements before final integration into production designs.

Supervisors Selection Notes

Select this component when a dedicated battery backup supervisor with a 2.63 V threshold is required. The low quiescent current makes it suitable for power-sensitive designs. Consider the fixed reset delay and lack of manual reset options during system architecture planning. Verify that the 8-µDFN footprint aligns with existing PCB layout constraints and thermal management requirements.

Supervisors Part Context

This part belongs to the MAX16039 series of low-power voltage supervisors. It shares functional similarities with other Maxim Integrated supervisory ICs but is distinguished by its specific 2.63 V threshold and battery backup configuration. The series targets applications requiring reliable power management in space-constrained environments.
