MAX6356SZUT-T

Overview

The MAX6356SZUT-T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It functions as a triple-voltage monitor housed in a surface-mount SOT-23-6 package. The device monitors three distinct input supply voltages, with preset thresholds of 2.93V and 4.63V, plus one adjustable threshold. It features an active-low push-pull reset output referenced to VCC1. Key electrical parameters include a minimum power-on reset pulse width of 100ms, a maximum operating voltage of 5.5V, and a quiescent supply current of 20µA. The component operates within an extended temperature range of -40°C to +85°C.

Feature Summary

• Monitors up to three independent power-supply voltages simultaneously
• Provides active-low debounced manual reset input for system control
• Maintains valid reset outputs as long as any monitored supply exceeds 1.0V

Applications

• Multi-rail embedded systems requiring simultaneous voltage supervision
• Portable electronics utilizing multiple logic and memory voltage domains
• Industrial control units needing reliable power-fail detection

Procurement Notes

Verify the specific suffix 'SZ' against official Maxim Integrated documentation to confirm exact threshold configurations and pinout compatibility. Ensure the ordering part number matches the required voltage levels and package type. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer before finalizing procurement plans.

Selection Notes

Select this component when designing systems that require monitoring of three distinct voltage rails within a compact footprint. It is suitable for applications demanding low standby current and precise factory-set thresholds. Consider the SOT-23-6 package constraints and the specific voltage requirements of the target application during integration.

Part Context

This part belongs to the MAX6351–MAX6360 series of dual/triple-voltage microprocessor supervisors. These devices are designed to improve system reliability by replacing discrete components with integrated solutions. The series offers various threshold combinations and package options to accommodate diverse multi-supply architectures.

Replacement Considerations

Direct substitutes within the same family include MAX6355LSUT+T and MAX6357LSUT+T, provided their specific voltage thresholds and output configurations match the design requirements. Verify functional equivalence regarding reset polarity and timeout periods.
