MAX16058ATA31+T

Supervisors Overview

The MAX16058ATA31+T is a voltage supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It operates within a supply voltage range of 1.1 V to 5.5 V and consumes only 125 nA of quiescent current. The device features a reset threshold voltage of 3.075 V with an accuracy of 2.5%. It provides an active low, open-drain output and includes a manual reset input alongside a watchdog timer function. The reset delay time is specified at 14.18 ms. Designed for surface-mount installation, it is housed in a compact DFN-8 package and supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Includes a manual reset input for user-controlled initialization
• Features capacitor-adjustable reset timing capabilities
• Provides ultra-low power consumption suitable for battery-operated systems

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing reliable power supervision
• Industrial control units operating in harsh environments
• Automotive electronics demanding high temperature stability

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the threshold voltage variant matches the design requirement of 3.075 V. Check current availability status as distribution may be limited. Ensure compatibility with the DFN-8 footprint during PCB layout. Validate RoHS compliance documentation if required for your region.

Supervisors Selection Notes

Select this component when low standby current is critical for power management. The integrated watchdog and manual reset simplify circuit design compared to discrete solutions. Consider the DFN-8 package size constraints against available board space. Verify that the 3.075 V threshold aligns with the monitored rail voltage. Evaluate thermal performance within the specified -40°C to +125°C operational range.

Supervisors Part Context

This part belongs to the MAX16058 family of NanoPwr supervisory circuits. The series is characterized by minimal current draw and flexible configuration options. It complements other Maxim Integrated PMIC solutions for comprehensive power management strategies. The DFN-8 package offers a small form factor advantage over larger SOIC alternatives.

Supervisors Replacement Considerations

Consult official datasheets for direct pin-compatible substitutes within the MAX16058 series. Verify threshold voltage differences if replacing with other variants like MAX16058ATA22+. Ensure functional equivalence regarding watchdog and manual reset features.
