MAX6351LSUT

Overview

The MAX6351LSUT+T is a dual-channel microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It provides precision monitoring for two independent power-supply voltages with factory-set reset thresholds. The device features active-low push-pull reset outputs referenced to VCC1 and VCC2, ensuring reliable system resets when input supplies drop below their respective preset levels. It includes a debounced manual-reset input and operates over an extended temperature range of -40°C to +85°C in a compact SOT-23-6 surface-mount package.

Feature Summary

• Dual-channel voltage supervision with independent reset outputs referenced to separate supply rails
• Active-low push-pull output configuration for robust drive capability
• Debounced manual-reset input compatible with TTL/CMOS logic levels
• Extended industrial operating temperature range for harsh environments

Applications

• Multi-rail embedded system power management
• Industrial control unit voltage supervision
• Telecommunications equipment power integrity monitoring
• Automotive electronic module reset generation

Procurement Notes

Verify the complete part number including suffixes such as +T for tape-and-reel packaging against official manufacturer documentation. Confirm RoHS compliance status and current lifecycle stage directly with Analog Devices or authorized distributors. Ensure the specific threshold voltage variants match the design requirements before procurement.

Selection Notes

Select this component when simultaneous monitoring of two distinct voltage rails is required with independent reset assertions. The push-pull output architecture suits applications needing strong drive currents without external pull-up resistors. Verify that the fixed threshold voltages align with the target supply rails to ensure accurate detection of under-voltage conditions.

Part Context

This device belongs to the MAX6351–MAX6360 family of µP supervisors designed to replace discrete monitoring components. The series improves system reliability through integrated precision thresholds and reduced board space. The MAX6351 specifically addresses dual-supervision needs within the broader portfolio that includes triple-channel and watchdog-enabled variants.

Replacement Considerations

Cross-reference with MAX6351TZUT+T or MAX6351UVUT+T for alternative threshold configurations within the same package. Verify pinout compatibility and electrical characteristics against the original datasheet before substitution.
