MAX16039LLA26+T

Supervisors Overview

The MAX16039LLA26+T is a low-power voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of up to 5.5V and features a fixed threshold voltage of 2.63V for monitoring input lines. The device provides an active-low, open-drain output with a reset delay time of 280ms. Designed for battery backup applications, it consumes only 22µA of operating current. The component is housed in an 8-pin UDFN package and supports surface-mount installation across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Provides reliable power-supply supervision for microprocessor systems
• Optimized for low-power operation in battery-backed environments
• Features a compact footprint suitable for space-constrained designs

Supervisors Applications

• Microprocessor reset circuits
• Battery backup power management
• Portable electronic devices requiring low quiescent current

Supervisors Procurement Notes

Verify the specific suffix '26' corresponds to the required 2.63V threshold during procurement. Confirm availability status as distribution channels may indicate limited stock or end-of-life conditions. Ensure the UDFN-8 package variant matches the PCB layout requirements. Cross-reference the manufacturer's latest datasheet revision to confirm pinout compatibility before finalizing orders.

Supervisors Selection Notes

Select this component when a fixed 2.63V trip point is required for system supervision. Consider the 22µA supply current for battery-sensitive applications. The open-drain output requires an external pull-up resistor. Verify that the 280ms timeout meets the system's initialization timing constraints. Ensure the operating voltage does not exceed the 5.5V maximum rating.

Supervisors Part Context

This part belongs to the MAX16039 series of low-power voltage supervisors. The series offers various threshold voltages and packages. The LLA26 suffix specifically denotes the 2.63V threshold and UDFN-8 packaging configuration within the broader product family designed for portable and battery-operated electronics.

Supervisors Replacement Considerations

Check for direct substitutes within the MAX16039 series offering different thresholds or packages. Verify functional equivalence with other Maxim Integrated supervisor ICs featuring similar voltage ranges and output types.
