MAX16057ATT23+

Supervisors Overview

The MAX16057ATT23+ is a nanoPower supervisory circuit designed for monitoring single voltage rails within the 1.1V to 5.5V range. It features a factory-set reset threshold of 2.313V and provides an active-low, push-pull output. The device incorporates adjustable reset and watchdog timeout functions via external capacitors, eliminating the need for internal timing components. Operating across a temperature range of -40°C to +125°C, it utilizes a 6-TDFN (3x3) package with an exposed pad for efficient thermal management and compact board space utilization.

Supervisors Feature Summary

• Ultra-low quiescent current consumption enables extended battery life in portable applications
• Adjustable reset and watchdog timeouts are configured using external capacitors
• Active-low push-pull output ensures robust drive capability for downstream logic

Supervisors Applications

• Portable consumer electronics requiring low power standby modes
• Battery-powered embedded systems needing reliable brown-out protection
• Industrial control units operating in wide temperature environments

Supervisors Procurement Notes

Verify the specific suffix '23' confirms the 2.313V threshold setting against your design requirements. Ensure the 6-TDFN footprint matches your PCB layout guidelines. Confirm RoHS compliance status if required by your manufacturing standards. Cross-reference the datasheet revision date to ensure compatibility with your system specifications.

Supervisors Selection Notes

Select this component when a fixed threshold near 2.3V is required without external resistor dividers. It is suitable for designs prioritizing minimal static current draw over programmable thresholds. Consider the external capacitor requirement for timeout settings when evaluating board space constraints compared to internally timed alternatives.

Supervisors Part Context

This part belongs to the MAX16056/MAX16057/MAX16058 family of nanoPower supervisors. While the MAX16056 includes a comparator and the MAX16058 adds a watchdog timer, the MAX16057 focuses on basic supervision with adjustable timing. All variants share similar low-power characteristics and packaging options within the Maxim Integrated portfolio.

Supervisors Replacement Considerations

Direct substitutes include other MAX16057 variants with different threshold voltages, such as the MAX16057ATT17+T (1.665V). Verify that alternative parts maintain the same TDFN-6 package and electrical characteristics to ensure pin-to-pin compatibility.
