MAX6888METE

Supervisors Overview

The MAX6888METE+ is a quad power-supply supervisor from Analog Devices/Maxim Integrated, housed in a TQFN-16 package. It monitors four independent voltage rails with an accuracy of 1%. The device features active-low open-drain outputs and a manual reset input. It includes a watchdog timer and operates within a supply voltage range up to 5.8V. The reset delay time is 200 ms, and the operating temperature range spans from -40°C to +85°C. Supply current is 900 uA.

Supervisors Feature Summary

• Monitors four independent power-supply inputs simultaneously
• Integrates a watchdog timer for system reliability
• Provides manual reset capability via dedicated input
• Delivers active-low open-drain status outputs

Supervisors Applications

• Multi-rail embedded system power supervision
• Industrial control board voltage monitoring
• Telecommunications equipment power management
• Portable electronic device power integrity verification

Supervisors Procurement Notes

Verify the specific suffix against official datasheets to confirm threshold voltages and package variations. Confirm RoHS compliance status through manufacturer documentation. Check component lifecycle status as some variants may be discontinued. Ensure ESD handling procedures are followed during assembly due to the surface-mount nature of the TQFN-16 package.

Supervisors Selection Notes

Select this component when simultaneous monitoring of four distinct voltage rails is required. Consider the 1% accuracy specification for precision applications. Evaluate the 900 uA supply current against low-power design constraints. Verify that the 200 ms reset delay aligns with system startup timing requirements.

Supervisors Part Context

This part belongs to the MAX6888 series of hex and quad power-supply supervisors. It is designed for applications requiring comprehensive multi-voltage monitoring in compact form factors. The TQFN-16 package allows for space-efficient PCB layouts while maintaining robust thermal performance for industrial environments.

Supervisors Replacement Considerations

Check for direct pin-compatible alternatives within the same product family. Verify functional equivalence regarding watchdog timeout periods and reset delays. Confirm that replacement parts support the same number of monitored inputs and output configurations.
