MAX6357TYUT

Overview

The MAX6357TYUT+T is a triple uPower Supervisor manufactured by Analog Devices Inc./Maxim Integrated. It monitors three input voltages with thresholds of 1.8 V, 2.5 V, and 3 V. The device features active low push-pull outputs and manual reset capability. It operates within a supply voltage range up to 5.5 V and has a reset delay time of 280 ms. The quiescent current is 20 uA. It functions in temperatures from -40 C to +85 C and is housed in an SOT-23-6 package.

Feature Summary

• Triple voltage monitoring for multiple power rails
• Low quiescent current consumption for battery applications
• Manual reset input for system control

Applications

• Portable electronic devices requiring multi-voltage supervision
• Battery-powered systems needing low standby current
• Embedded controllers requiring manual reset functionality

Procurement Notes

Verify the exact suffix against official documentation as availability varies. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Check for obsolescence notices or lifecycle changes before finalizing procurement plans. Ensure the specific threshold voltages match the design requirements.

Selection Notes

Select this component when triple voltage supervision is required with minimal power consumption. Verify that the specified threshold voltages (1.8 V, 2.5 V, 3 V) align with the target power rails. Consider the SOT-23-6 package size constraints. Ensure the operating temperature range meets the environmental conditions of the application.

Part Context

This part belongs to the MAX6357T series of supervisory circuits designed for low-power applications. It provides essential protection for microprocessors and memory systems by detecting under-voltage conditions across three independent channels.

Replacement Considerations

Check for direct pin-to-pin replacements within the MAX6357 family with different threshold options. Verify compatibility with existing PCB layouts and electrical specifications before substitution.
