MAX6355RWUT+T

Overview

The MAX6355RWUT+T is a multi-voltage supervisor IC from the MAX6355L series, manufactured by Analog Devices Inc./Maxim Integrated. It monitors up to three independent voltage rails using an SOT-23-6 surface-mount package. The device features active-low open-drain outputs with a manual reset input and integrated watchdog timer functionality. Key electrical specifications include a maximum supply voltage of 5.5 V, a typical operating current of 20 µA, and a reset delay time of 180 ms. Threshold accuracy is specified at 1.5%, with operating temperatures ranging from -40°C to +85°C.

Feature Summary

• Monitors multiple independent voltage rails simultaneously
• Includes manual reset input for system control
• Integrates watchdog timer for fault detection
• Provides active-low open-drain output signals

Applications

• Portable equipment requiring battery monitoring
• Communication systems needing power supervision
• Industrial control units with multiple voltage domains
• Embedded systems requiring watchdog protection

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lot traceability before integration. Check for obsolescence notices as availability may vary. Ensure storage conditions meet semiconductor handling standards to prevent degradation prior to assembly.

Selection Notes

Select this part when simultaneous monitoring of multiple voltage rails is required in a compact footprint. Consider the 1.5% threshold accuracy and 180 ms reset delay for timing-sensitive applications. Evaluate the 20 µA quiescent current against battery life requirements. Verify that the SOT-23-6 package fits the PCB layout constraints.

Part Context
