MAX6709JUB+

Supervisors Overview

The MAX6709JUB+ is a low-voltage, high-accuracy quad voltage monitor manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range of 1.1V to 5.5V and features four independent voltage monitoring channels with adjustable thresholds. The device provides an active-low, open-drain reset output with a typical reset delay time of 30 microseconds. It is housed in a compact uMAX-10 surface-mount package and supports power-fail detection. The component is designed for applications requiring precise supervision of multiple power rails in space-constrained environments.

Supervisors Feature Summary

• Provides simultaneous monitoring of four independent voltage inputs with high accuracy

Supervisors Procurement Notes

Verify the specific suffix JUB against official Analog Devices documentation to confirm pinout and electrical characteristics. Confirm RoHS compliance status through current manufacturer declarations. Check for obsolescence notices or lifecycle changes directly from the supplier. Ensure the uMAX-10 package footprint matches your PCB design constraints. Validate that the adjustable threshold configuration meets your circuit's specific voltage monitoring needs.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision in a small form factor. Consider the adjustable threshold capability if fixed-voltage monitors do not match your system's specific voltage levels. Evaluate the 30-microsecond reset delay against your system's startup timing requirements. Ensure the active-low open-drain output interface is compatible with your microcontroller or logic input. Verify that the operating temperature range suits your intended application environment.
