MAX16049ETN+

Supervisors Overview

The MAX16049ETN+ is a system manager supervisory circuit featuring an integrated 10-bit analog-to-digital converter (ADC) with 1% accuracy. It monitors up to twelve inputs, including eight voltage rails and four temperature sensors. The device provides EEPROM-based programmability for customizing reset thresholds and timing parameters. It operates within a supply voltage range of 2.7V to 5.5V and supports multiple reset output configurations. The component is housed in a 56-lead TQFN package.

Supervisors Feature Summary

• Integrates a high-accuracy 10-bit ADC for simultaneous monitoring of multiple power rails and thermal conditions
• Features non-volatile EEPROM memory allowing in-circuit programming of reset thresholds and watchdog timers
• Supports flexible reset output options including open-drain and push-pull configurations for diverse system requirements

Supervisors Applications

• Server and workstation power management systems
• Storage area network equipment
• Telecommunications infrastructure hardware

Supervisors Procurement Notes

Verify the specific suffix ETN+ confirms the 56-TQFN package variant. Confirm RoHS compliance status through official documentation. Check current lifecycle status as obsolescence notices may apply. Ensure compatibility with existing board layout constraints for the exposed pad thermal design.

Supervisors Selection Notes

Select this component when multi-channel voltage and temperature monitoring is required alongside precise threshold control. The integrated ADC reduces external sensor count. Verify that the 56-pin footprint fits the mechanical design. Consider the EEPROM programming interface availability during system development.

Supervisors Part Context

This part belongs to the Maxim Integrated MAX16049 family of system managers. These devices are designed for complex embedded systems requiring comprehensive power integrity monitoring. The ETN+ designation specifies the surface-mount package type and lead-free manufacturing process compliant with environmental standards.

Supervisors Replacement Considerations

The MAX16049ACB+ is a documented alternative within the same family, offering similar functionality in a different package configuration.
