MAX16057ATT46+

Supervisors Overview

The MAX16057ATT46+T is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for monitoring single voltage rails. It operates within an input voltage range of 2.25V to 28V and features a fixed threshold voltage of 4.6V. The device provides an active-low push-pull reset output with a selectable timeout period. It is housed in a compact 6-TDFN (3x3) package with an exposed pad, supporting surface-mount installation. The component functions reliably across an extended industrial temperature range from -40°C to +125°C, ensuring stable performance in demanding electronic environments.

Supervisors Feature Summary

• Provides precise voltage supervision with a fixed 4.6V threshold for reliable system monitoring
• Features a configurable reset timeout period to accommodate various power-up sequencing requirements
• Delivers an active-low push-pull reset signal for direct interface with digital logic circuits

Supervisors Applications

• Portable equipment requiring low-power voltage supervision
• Battery-powered systems needing reliable power-fail detection
• Industrial control units operating in extreme temperature conditions

Supervisors Procurement Notes

Verify the complete part number including the trailing 'T' for tape-and-reel packaging when ordering. Confirm that the 4.6V threshold aligns with the specific supply rail being monitored. Ensure the PCB footprint matches the 6-TDFN (3x3) dimensions and thermal pad requirements. Check current availability status as supply may be limited for this specific variant.

Supervisors Selection Notes

Select this component when a fixed 4.6V threshold is required rather than adjustable options. Consider the 6-TDFN package size constraints against available board space. Evaluate the need for a selectable timeout feature versus fixed delay alternatives. Verify compatibility with the system's logic levels given the push-pull output configuration.

Supervisors Part Context

This component belongs to the MAX16056-59 series of NanoPwr supervisory circuits. These devices are engineered for ultra-low power consumption in portable applications. The series offers various threshold voltages and package options to suit different design needs while maintaining high accuracy and reliability standards typical of Maxim Integrated power management solutions.

Supervisors Replacement Considerations

Check the official MAX16056-59 datasheet for pin-compatible alternatives with different threshold voltages or timeout configurations. Verify if other members of the MAX16057 family offer the same 6-TDFN package but with adjusted electrical characteristics suitable for the target application.
