MAX16056ATA26+

Supervisors Overview

The MAX16056ATA26+ is a voltage supervisory circuit from Analog Devices/Maxim Integrated, housed in an 8-pin TDFN (3x3mm) package. It features a fixed threshold voltage of 2.6V for monitoring a single input channel. The device provides an active-low push-pull output and includes a manual reset input. Key electrical parameters include a maximum supply voltage of 5.5V, a quiescent current of 125nA, and a reset delay time of 14.18ms. It operates within a temperature range of -40°C to +125°C with an accuracy of 2.5%.

Supervisors Feature Summary

• Capacitor-adjustable reset times allow customization of the reset delay duration via an external capacitor.
• Integrated watchdog timer ensures system reliability by detecting software failures or lockups.
• Manual reset input enables direct user control over the reset state independent of voltage conditions.

Supervisors Applications

• Embedded systems requiring precise power supply monitoring
• Microprocessor reset circuits in industrial environments
• Battery-powered devices needing low standby current

Supervisors Procurement Notes

Verify the specific suffix 'ATA26+' to confirm the 2.6V threshold and push-pull output configuration. Ensure compatibility with the 8-TDFN footprint during PCB layout. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when a fixed 2.6V threshold is required alongside adjustable reset timing and watchdog functionality. The push-pull output drives loads directly without external pull-ups. Consider the 125nA quiescent current for battery-sensitive designs. Verify that the 8-TDFN package fits the available board space constraints.

Supervisors Part Context

Part of the MAX16058/MAX16059 family of supervisory circuits designed for low-power applications. Shares similar features like capacitor-adjustable resets but differs in threshold voltage and output stage configuration compared to other variants in the series.

Supervisors Replacement Considerations

Check for MAX16056ATA26+T as a tape-and-reel variant if different packaging is needed. Verify pinout compatibility with other MAX1605x series parts before substitution.

Supervisors FAQ

How is the reset delay time adjusted?

The reset delay time is adjusted by connecting an external capacitor to the RESET/CAP pin. The value of this capacitor determines the delay duration according to the datasheet specifications.

What is the output type of the MAX16056ATA26+?

The MAX16056ATA26+ features an active-low push-pull output, which can source and sink current without requiring an external pull-up resistor.
