MAX16040LLA29+T

Supervisors Overview

The MAX16040LLA29+T is a voltage supervisor IC designed for battery backup circuit applications. It monitors a single power supply input with a threshold voltage of 2.93V and an overvoltage threshold of 3V. The device features a push-pull, totem pole output that asserts low when the monitored voltage falls below the reset threshold or exceeds the overvoltage limit. It includes a fixed reset delay time of 140ms minimum to ensure stable operation during power transitions. Operating from a supply range up to 5.5V, it draws minimal current and functions within a temperature range of -40°C to +85°C.

Supervisors Feature Summary

• Monitors a single power supply rail for under-voltage and over-voltage conditions
• Provides a low-active push-pull output signal for system reset control
• Integrates a fixed reset delay timer to prevent false triggering during power-up

Supervisors Applications

• Battery backup switching circuits
• Portable electronic devices requiring power supervision
• Embedded systems monitoring main power rails

Supervisors Procurement Notes

Verify component authenticity through authorized channels as this part may be subject to limited availability or obsolescence notices. Confirm package integrity and RoHS compliance status upon receipt. Cross-reference datasheet revisions to ensure compatibility with existing design specifications before final procurement decisions.

Supervisors Selection Notes

Select this component when a compact solution for single-rail supervision is required in battery-powered designs. The 8-µDFN package suits space-constrained layouts. Ensure the 2.93V threshold aligns with the specific battery cutoff requirements of the target application.

Supervisors Part Context

Part of the MAX16033-40 family of low-power supervisors. Shares functional similarities with the MAX16039 but differs in output type and reset timing characteristics. Designed for integration into portable electronics where power management efficiency and small form factor are critical design constraints.

Supervisors Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout and electrical parameter compatibility if considering alternative vendors or updated series members.
