MAX16056ATA31+T

Supervisors Overview

The MAX16056ATA31+T is a supervisory circuit featuring a watchdog timer and adjustable reset timeout via external capacitors. It operates within a supply voltage range of 1.1V to 5.5V with a fixed threshold of 3.075V. The device provides an active-low, push-pull reset output in an 8-pin TDFN package. Key specifications include a maximum supply current of 125nA and a watchdog select feature for flexible timing configurations.

Supervisors Feature Summary

• Adjustable reset and watchdog timeouts using external capacitors
• Integrated watchdog timer with watchdog select functionality
• Active-low push-pull reset output

Supervisors Applications

• Safety-critical automotive applications
• CPU supervision systems
• Robust power-system supervision

Supervisors Procurement Notes

Verify the specific suffix 'A31' corresponds to the 3.075V threshold requirement. Confirm the TDFN-8 package dimensions match the PCB footprint. Ensure the active-low output polarity aligns with the target microcontroller's reset input logic. Cross-reference the datasheet revision date to confirm compatibility with current design standards.

Supervisors Selection Notes

Select this component when a low quiescent current supervisor with configurable timing is required. The fixed 3.075V threshold suits 3.3V systems. The capacitor-adjustable timeout allows customization without changing part numbers. Verify that the external capacitor values fit within the available board space and temperature stability requirements.

Supervisors Part Context

This part belongs to the MAX16056/MAX16058 family of supervisory circuits designed for robust system monitoring. These devices are engineered for safety-critical environments, offering precise voltage detection and reliable watchdog protection. The family shares core architecture but differs in thresholds and pin configurations.

Supervisors Replacement Considerations

Check for direct substitutes within the MAX16056 series with different voltage thresholds if system rails vary. Ensure any replacement maintains the TDFN-8 package and active-low output characteristics. Verify that the new part supports the same capacitor-based timeout adjustment method.
