MAX16009TG+

Supervisors Overview

The MAX16009TG+ is a low-voltage, high-accuracy quad window voltage supervisor manufactured by Analog Devices / Maxim Integrated. It monitors four independent input voltages and provides an active-low open-drain reset output when any monitored rail falls below or exceeds its respective threshold. The device features adjustable overvoltage thresholds and a fixed undervoltage threshold of 394 mV. It operates within a supply voltage range of 1 V to 5.5 V and includes a manual reset input. The IC offers 1.5% accuracy, a 200 ms reset delay, and consumes 45 uA of quiescent current. It is housed in a TQFN-24 package and functions reliably across an industrial temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Monitors four independent voltage rails with high accuracy for comprehensive power system supervision
• Features adjustable overvoltage thresholds and a fixed low undervoltage threshold for flexible configuration
• Includes a manual reset input allowing external control over the reset state generation

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for portable electronic devices
• Industrial control systems requiring reliable power integrity checks

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for end-of-life notifications prior to procurement. Ensure the TQFN-24 package variant matches design requirements. Review datasheet specifications for thermal performance and electrical limits to validate suitability for the target application environment.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required with high precision. The adjustable overvoltage thresholds allow customization for specific circuit needs. Consider the 45 uA quiescent current for battery-powered applications. Verify that the TQFN-24 package fits the PCB layout constraints and that the operating temperature range meets environmental demands.

Supervisors Part Context

This part belongs to the MAX16009 series of voltage supervisors from Analog Devices / Maxim Integrated. It is designed for low-voltage applications requiring multiple channel monitoring. The series focuses on providing accurate supervision with minimal power consumption. The TG+ suffix indicates a lead-free, halogen-free version compliant with RoHS standards, packaged in a TQFN-24 format suitable for surface-mount assembly.

Supervisors Replacement Considerations

Check for pin-compatible alternatives within the MAX16006 or MAX16003 series if different channel counts are acceptable. Verify that substitute parts support the same TQFN-24 package and meet the 1.5% accuracy requirement. Ensure replacement components offer similar quiescent current and operating temperature ranges.
