MAX6357LSUT+T

Overview

The MAX6357LSUT+T is a dual/triple-voltage microprocessor supervisory circuit in a SOT-23-6 package. It monitors two or three input supplies with thresholds of 2.93V and 4.63V, featuring active-low push-pull outputs referenced to VCC2. Key parameters include a maximum supply voltage of 5.5V, a reset delay of 180ms, and an operating current of 20µA. The device operates from -40°C to +85°C with 1.5% accuracy and includes a manual reset input.

Feature Summary

• Monitors multiple power-supply voltages with precision factory-set thresholds
• Provides active-low push-pull reset outputs referenced to specific supply rails
• Includes debounced manual-reset input for system control

Applications

• Embedded systems requiring multi-rail power supervision
• Industrial equipment monitoring critical voltage levels
• Telecommunications infrastructure power management

Procurement Notes

Verify the exact suffix 'LSUT' against the manufacturer's official datasheet to confirm threshold specifications and pinout compatibility. Ensure the component meets RoHS requirements if mandated by your assembly process. Cross-reference the part number with Analog Devices documentation to validate availability status and lead times before finalizing procurement plans.

Selection Notes

Select this component when precise monitoring of dual or triple voltage rails is required within a compact SOT-23-6 footprint. The push-pull output configuration eliminates the need for external pull-up resistors, simplifying board layout. Verify that the monitored voltage levels align with the available factory-set thresholds to ensure accurate system reset behavior under all operating conditions.

Part Context

This device belongs to the MAX635x series of microprocessor supervisors designed to improve system reliability. Unlike discrete solutions, it integrates multiple monitoring functions into a single IC. The series offers various threshold options and package types, providing designers with flexible configurations for diverse voltage monitoring applications across extended temperature ranges.

Replacement Considerations

Check the MAX6358LSUT+T for similar dual/threshold functionality but note its open-drain output type differs from the MAX6357's push-pull outputs. Verify pin compatibility and electrical characteristics before substitution.
