MAX16009TG+T

Supervisors Overview

The MAX16009TG+T is a low-voltage, high-accuracy quad window voltage monitor manufactured by Analog Devices Inc./Maxim Integrated. It monitors four independent supply voltages and activates fault signals when inputs exceed overvoltage or fall below undervoltage thresholds. The device operates within a supply voltage range of 1 V to 5.5 V and features an active low, open-drain output with a manual reset capability. It includes a fixed reset delay time of 200 ms and maintains an accuracy of 1.5%. Designed for surface-mount installation in TQFN-24 packages, it supports a wide operating temperature range from -40°C to +125°C while consuming only 45 µA of quiescent current.

Supervisors Feature Summary

• Monitors four independent supply voltages simultaneously using window detection architecture
• Provides active low, open-drain fault signaling with manual reset functionality
• Operates across a wide industrial temperature range with high voltage accuracy

Supervisors Applications

• Multi-rail power system supervision in embedded systems
• Voltage monitoring for portable electronic devices
• Industrial control board power integrity verification

Supervisors Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging configuration distinct from tube variants. Confirm RoHS compliance status through official documentation as required for assembly processes. Ensure the TQFN-24 footprint matches the target PCB layout dimensions precisely before finalizing procurement orders.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required without external comparator circuitry. The low quiescent current makes it suitable for battery-powered applications where power efficiency is critical. Verify that the adjustable overvoltage threshold meets the specific system requirements compared to fixed-threshold alternatives.

Supervisors Part Context

This part belongs to the MAX16009 series of window voltage monitors designed for low-voltage applications. It complements other supervisory ICs by offering multi-channel monitoring in a compact form factor. The series focuses on providing reliable fault detection for complex power architectures found in modern consumer and industrial electronics.

Supervisors Replacement Considerations

Check for direct pin-compatible upgrades within the MAX16009 family if package availability changes. Evaluate alternative quad-window monitors from the same manufacturer ensuring identical output logic and reset timing characteristics are maintained.
