MAX6356SZUT+T

Overview

The MAX6356SZUT+T is a microprocessor supervisor IC from the MAX6351–MAX6360 series, designed to monitor multiple power-supply voltages and improve system reliability. It features three monitored inputs with preset thresholds of 2.93V, 4.63V, and an adjustable voltage. The device provides active-low reset outputs in a push-pull/totem pole configuration. It includes a debounced manual reset input and operates within an extended temperature range of -40°C to +85°C. The component is housed in a surface-mount SOT-23-6 package.

Feature Summary

• Monitors up to three independent supply voltages simultaneously
• Provides active-low reset outputs with push-pull drive capability
• Includes a debounced manual reset input for TTL/CMOS compatibility
• Operates with low supply current consumption

Applications

• Multi-voltage power supply supervision in embedded systems
• Microprocessor reset circuitry for industrial control applications
• System reliability monitoring in portable electronic devices

Procurement Notes

Verify the specific suffix 'SZ' against official Analog Devices documentation to confirm exact threshold levels and package variant, as distributor listings may not fully detail suffix-specific electrical parameters. Ensure the source document explicitly supports the 'SOT-23-6' package and 'push-pull' output type for this precise part number before procurement.

Selection Notes

Select this component when simultaneous monitoring of three distinct voltage rails is required. The adjustable threshold option allows flexibility for non-standard voltage levels. Verify that the push-pull output drive strength meets the load requirements of the connected microprocessor or logic gate without external buffering.

Part Context

This part belongs to the MAX635x family of multi-supervisor ICs. These devices integrate multiple voltage monitors into a single small footprint, replacing discrete components. The MAX6356 specifically adds a third monitor channel compared to dual-channel variants, offering enhanced supervision for complex power architectures.

Replacement Considerations

Check for MAX6356LSUT+T or MAX6356MSUT+T if different threshold configurations are acceptable. Verify pinout compatibility and output drive characteristics before substituting.
