MAX16055EAUB+

Supervisors Overview

The MAX16055EAUB+ is a hex voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors six independent power supply rails within a compact UMAX-10 surface-mount package. The device features active-low open-drain outputs and supports manual reset functionality. Key electrical parameters include a maximum supply voltage of 5.5 V, a reset delay time of 200 ms, and an accuracy of 1.5%. Threshold voltages are fixed at 1.8 V, 2.5 V, and 3.3 V, with an adjustable option. Operating current ranges from 25 uA to 55 uA, and the component operates reliably between -40 C and +125 C.

Supervisors Feature Summary

• Monitors up to six independent voltage inputs simultaneously for comprehensive system supervision.
• Provides active-low open-drain reset signals compatible with standard logic interfaces.
• Includes a manual reset input pin allowing external control over the reset state.

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Multi-rail voltage supervision in industrial control units
• System integrity verification in portable electronic devices

Supervisors Procurement Notes

Verify availability status carefully as this part may be subject to limited supply or discontinuation. Confirm that the specific threshold voltage configuration matches the design requirements, as options vary across the MAX16055 family. Ensure compatibility with the target PCB footprint, specifically the UMAX-10 package dimensions. Check for RoHS compliance documentation if required by regional regulations.

Supervisors Selection Notes

Select this component when simultaneous monitoring of multiple low-voltage rails is required in space-constrained designs. The UMAX-10 package offers a small form factor suitable for dense layouts. Consider the fixed versus adjustable threshold options based on the specific voltage levels present in the application. Verify that the 200 ms reset delay aligns with the startup timing requirements of the monitored microprocessor or logic circuits.

Supervisors Part Context

The MAX16055 series belongs to Maxim Integrated's portfolio of ultra-small voltage supervisors designed for complex digital systems. This family provides flexible monitoring capabilities for various power architectures. The EAUB+ suffix indicates a specific threshold configuration and lead-free packaging compliant with environmental standards. It serves as a critical component for ensuring reliable system initialization and operation under varying power conditions.

Supervisors Replacement Considerations

Check for other MAX16055 variants with different threshold combinations if the exact 1.8V/2.5V/3.3V mix is unavailable. Verify pinout compatibility before substituting with similar hex supervisors from other manufacturers. Ensure the replacement maintains the same UMAX-10 package and electrical characteristics such as operating temperature range and supply voltage limits.
