MAX16058ATA27+T

Supervisors Overview

The MAX16058ATA27+T is a supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated, designed for low-power voltage monitoring applications. It features an ultra-low quiescent current of 125nA and integrates Capacitor-Adjusted Reset (CAR) technology to minimize external component count. The device provides a reset output with a threshold voltage of 2.7V and utilizes an open-drain configuration. Packaged in a compact TDFN-8 form factor, it supports surface-mount installation and operates within standard industrial temperature ranges, ensuring reliable system supervision.

Supervisors Feature Summary

• Ultra-low power consumption with 125nA supply current
• Capacitor-Adjusted Reset (CAR) technology for simplified design
• Open-drain reset output for flexible interfacing
• Compact TDFN-8 package for space-constrained boards

Supervisors Applications

• Portable battery-powered electronic devices
• Embedded systems requiring low standby current
• Industrial control units needing voltage supervision
• Consumer electronics with strict power budgets

Supervisors Procurement Notes

Verify the specific suffix +T indicates tape-and-reel packaging when ordering. Confirm the 2.7V threshold matches the target rail voltage. Check RoHS compliance status as required by regional regulations. Ensure the TDFN-8 footprint aligns with existing PCB layout constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when minimizing quiescent current is critical for extending battery life. The CAR feature reduces bill-of-materials cost by eliminating external resistors for reset timing. Compare against other MAX16058 variants if different voltage thresholds are needed. Ensure the open-drain output capability meets the logic level requirements of the monitored microcontroller or processor.

Supervisors Part Context

This part belongs to the MAX16058 family of NanoPwr supervisory circuits. The series is characterized by its ability to monitor single-supply voltages with minimal power draw. Variants within the family differ primarily in reset threshold voltages and package options, allowing designers to tailor supervision to specific application rails without changing the core architecture.

Supervisors Replacement Considerations

Direct substitutes include other MAX16058 variants with identical pinouts but different threshold voltages, such as MAX16058ATA17+T or MAX16058ATA41+T. Verify that any replacement maintains the 125nA current specification and CAR functionality to ensure compatibility with existing capacitor-based timing designs.
