MAX16056ATA31+

Supervisors Overview

The MAX16056ATA31+ is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 2.7 V to 5.5 V and features a fixed threshold voltage of 3.075 V. The device provides a single monitored input with an active low, push-pull output type. It is housed in an 8-TDFN (3x3) package and supports surface mount installation. The component functions effectively across an extended temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides accurate voltage monitoring with a fixed 3.075 V threshold for system supervision.
• Features an active low, push-pull output interface for direct logic connection.
• Incorporates capacitive debounce functionality to prevent false resets during power transitions.

Supervisors Applications

• Portable equipment requiring low standby current
• Battery-powered systems needing reliable power supervision
• Embedded controllers requiring reset signal generation

Supervisors Procurement Notes

Verify the specific suffix 'A31' corresponds to the required 3.075 V threshold and TDFN-8 package configuration. Confirm that the active low output polarity matches the target microcontroller or FPGA reset input requirements. Ensure the operating temperature range meets the environmental specifications of the final assembly. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Supervisors Selection Notes

Select this component when a fixed threshold near 3.1 V is required for 3.3 V systems. The low quiescent current makes it suitable for battery-operated devices. The TDFN-8 package offers a compact footprint for space-constrained applications. Verify that the push-pull output capability is necessary rather than open-drain configurations found in other variants.

Supervisors Part Context

This part belongs to the MAX1605x series of supervisory circuits designed for portable electronics. It integrates voltage monitoring and reset generation in a small form factor. The series is characterized by low power consumption and high accuracy, targeting applications where power efficiency and board space are critical constraints.

Supervisors Replacement Considerations

Check for MAX16056ATA30+ if a different threshold voltage is acceptable. Verify MAX16056ATA32+ for alternative threshold options. Ensure any substitute maintains the same TDFN-8 package and active low output polarity to preserve PCB layout compatibility.
