MAX16058ATA17+T

Supervisors Overview

The MAX16058ATA17+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 fixed reset threshold voltage of 1.665 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 an 8-DFN package and supports an operating temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Ultra-low power consumption of 125 nA enables extended battery life in portable applications.
• Integrated watchdog timer ensures system reliability through automated fault recovery.
• Manual reset input allows for external control over the reset state when required.
• Capacitor-adjustable reset timing provides flexibility in managing startup sequences.

Supervisors Applications

• Portable electronic devices requiring minimal standby current
• Battery-powered systems needing reliable voltage supervision
• Industrial equipment operating in extreme temperature environments

Supervisors Procurement Notes

Verify the specific suffix 'ATA17' corresponds to the exact 1.665 V threshold and TDFN-8 packaging configuration required for your design. Confirm that the active low open-drain output polarity matches your microcontroller's reset input requirements. Ensure compatibility with the 1.1 V to 5.5 V supply range across all expected operating conditions. Check for any lead-free or RoHS compliance documentation if mandated by your assembly process standards.

Supervisors Selection Notes

Select this component when ultra-low quiescent current is critical for battery-operated designs. The fixed 1.665 V threshold suits applications monitoring standard logic supplies. The inclusion of a watchdog timer and manual reset offers robust protection without additional discrete components. Consider the 8-DFN package size constraints during PCB layout planning to ensure adequate thermal dissipation and soldering reliability.

Supervisors Part Context

This part belongs to the MAX16058 NanoPwr family, designed for space-constrained, low-power applications. It integrates supervisor functions typically requiring multiple discrete parts into a single compact IC. The family emphasizes high accuracy and low current draw, making it suitable for modern portable electronics where power efficiency and board space are primary design drivers.

Supervisors Replacement Considerations

Check for MAX16058 variants with different threshold voltages if the 1.665 V level is unsuitable. Verify pinout compatibility with alternative supervisors in the same DFN-8 package. Ensure substitute parts offer comparable quiescent current and watchdog functionality to maintain system performance and reliability standards.
