MAX16191ATA00/VY+T

Supervisors Overview

The MAX16191ATA00/VY+T is a single-channel, ultra-high accuracy supervisory circuit designed to monitor low core system supply voltages. It features an open-drain or push-pull reset output that asserts when the monitored voltage falls below the threshold. The device operates within a supply voltage range of up to 5.5V and supports an operating temperature range of -40°C to +125°C. It is housed in an 8-TDFN (2x2) package with wettable flanks, suitable for surface mount applications.

Supervisors Feature Summary

• Ultra-high accuracy supervision for low core system supply voltages
• Configurable reset output options including open-drain and push-pull configurations
• Automotive grade qualification ensuring reliability under harsh conditions

Supervisors Applications

• Monitoring low core system supply voltages in automotive electronics
• System reset management in battery-operated devices
• Voltage supervision in high-reliability industrial control systems

Supervisors Procurement Notes

Verify the specific suffix 'ATA00/VY+T' against the manufacturer's current datasheet to confirm the exact threshold voltage and package variant. Ensure compatibility with AEC-Q100 requirements if used in automotive contexts. Check for lead time constraints as automotive-grade components may have longer availability periods compared to commercial grades.

Supervisors Selection Notes

Select this component when precise monitoring of low-voltage rails is required in space-constrained designs. The TDFN-8 package offers a compact footprint suitable for dense PCB layouts. Consider the reset output configuration needs; choose between open-drain or push-pull based on downstream logic interface requirements. Verify that the monitored voltage range aligns with the available threshold options.

Supervisors Part Context

This part belongs to the MAX16191 series of supervisory circuits from Analog Devices/Maxim Integrated. The series focuses on providing accurate voltage monitoring solutions for modern electronic systems requiring robust reset management. The specific variant includes automotive qualification, distinguishing it from commercial-grade counterparts in the same family.

Supervisors Replacement Considerations

Direct replacements must match the 8-TDFN package and AEC-Q100 qualification. Verify that alternative parts support the same supply voltage range and offer comparable accuracy levels. Ensure the reset output polarity and drive capability are compatible with the existing circuit design without requiring additional level shifting.
