MAX16058ATA28+

Supervisors Overview

The MAX16058ATA28+ 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 features a threshold voltage of 1.575 V. The device draws a typical quiescent current of 125 nA and includes a manual reset input alongside a watchdog timer function. It provides an active low, open-drain output with a reset delay time of 14.18 ms. Accuracy is specified at 2.5%, and it functions reliably across an operating temperature range from -40°C to +125°C in a DFN-8 package.

Supervisors Feature Summary

• Integrates a watchdog timer for system reliability monitoring
• Supports manual reset functionality via dedicated input pin
• Features ultra-low power consumption suitable for battery-operated applications

Supervisors Applications

• Portable electronic devices requiring extended battery life
• Embedded systems needing reliable power supervision
• Industrial control circuits operating in harsh thermal environments

Supervisors Procurement Notes

Verify the specific suffix '28+' against official Analog Devices documentation to confirm the exact threshold voltage and package variant. Ensure compatibility with existing board layouts regarding the DFN-8 footprint. Confirm RoHS compliance status through manufacturer certificates before integration into regulated products.

Supervisors Selection Notes

Select this component when precise voltage monitoring is required with minimal standby current draw. The integrated watchdog timer simplifies design complexity compared to discrete solutions. Consider the 1.575 V threshold relative to the target rail voltage to ensure proper triggering during brown-out events.

Supervisors Part Context

This part belongs to the MAX16058 series of supervisory circuits designed for low-power applications. It complements other Maxim Integrated PMIC offerings by providing essential reset generation capabilities without significant power overhead.

Supervisors Replacement Considerations

Consult official cross-reference guides for verified substitutes. Generic equivalents may lack the specific 125 nA quiescent current or watchdog integration.
