MAX6357LSUT

Overview

The MAX6357LSUT+T is a microprocessor supervisory circuit from the MAX6357 series, designed for monitoring multiple power supplies. It features three monitored inputs with threshold voltages of 1.8V, 2.5V, and 3V/3.3V/5V options. The device operates within a supply voltage range up to 5.5V and consumes only 20µA of quiescent current. It provides active-low push-pull reset outputs with a minimum reset pulse width of 100ms. The component supports manual reset functionality and operates across an extended temperature range of -40°C to +85°C in a compact SOT-23-6 package.

Feature Summary

• Monitors three independent voltage rails simultaneously
• Provides active-low push-pull reset outputs referenced to VCC
• Includes debounced manual reset input for system control
• Operates with ultra-low 20µA supply current

Applications

• Multi-voltage embedded systems requiring power supervision
• Microprocessor reset circuits in portable devices
• Industrial control boards with multiple power domains
• Communication equipment power management

Procurement Notes

Verify exact threshold voltage configuration as suffixes determine specific trip points. Confirm RoHS compliance status through official documentation. Check availability status as this part may be subject to limited supply or end-of-life conditions. Ensure pinout compatibility with target PCB footprint before integration.

Selection Notes

Select based on required voltage thresholds for each monitored rail. Consider output drive capability if connecting to high-capacitance loads. Verify operating temperature range matches application environment. Compare against alternative supervisors if watchdog timer or backup battery switching is required.

Part Context

Part of the MAX6351-MAX6360 family of dual/triple-voltage supervisors. Shares common architecture with MAX6357 variants differing primarily in threshold settings and package options. Designed to replace discrete monitoring components for improved reliability and accuracy.

Replacement Considerations

MAX6357TWUT+T offers similar triple-supervision with different threshold configurations. MAX6358LSUT+T includes additional watchdog timer functionality. Verify electrical parameters and pinout compatibility before substitution.
