MAX16998DAUA/V+T

Supervisors Overview

The MAX16998DAUA/V+T is a high-voltage microprocessor supervisory circuit featuring an adjustable watchdog timer. It monitors input voltages from 1.02V to 4.8V with a threshold of 1.255V and supports a maximum supply voltage of 40V. The device provides an open-drain reset output with a fixed delay of 116.09ms. Packaged in an 8-pin UMAX, it operates between -40°C and +125°C and holds AEC-Q100 qualification for automotive reliability.

Supervisors Feature Summary

• High-voltage tolerance up to 40V for direct system monitoring
• Adjustable watchdog timer functionality for processor supervision
• AEC-Q100 qualified for automotive environment reliability

Supervisors Applications

• Automotive electronic control units
• Industrial microprocessor systems
• High-voltage embedded controllers

Supervisors Procurement Notes

Verify the specific suffix 'V+' indicates lead-free compliance and RoHS adherence per manufacturer standards. Confirm package integrity for the UMAX-8 form factor during inspection. Ensure compatibility with existing PCB footprints before integration. Check current availability status as distribution may be limited or subject to factory order constraints.

Supervisors Selection Notes

Select this component when system inputs exceed standard 5V logic levels but require precise low-voltage monitoring. The integrated watchdog feature simplifies firmware design by handling timeout resets independently. Verify that the 116.09ms reset delay aligns with system startup requirements. Ensure the operating temperature range meets the environmental conditions of the target application.

Supervisors Part Context

This part belongs to the MAX16998A series of supervisory circuits designed for demanding applications. It complements other Maxim Integrated power management solutions by providing robust fault detection. The series emphasizes low quiescent current and high input voltage capability, addressing needs in automotive and industrial sectors where standard supervisors fail.

Supervisors Replacement Considerations

Check for MAX16997 variants if lower voltage thresholds are required. Verify pinout compatibility with alternative UMAX-8 packages before substitution.
