MAX6356SZUT

Overview

The MAX6356SZUT+T is a triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It features three active-low push-pull reset outputs with factory-set thresholds of 2.93V, 4.63V, and an adjustable voltage monitor input. The device provides a minimum 100ms power-on reset pulse width and includes a debounced manual reset input. It operates within a temperature range of -40°C to +85°C and is available in a surface-mount SOT-23-6 package.

Feature Summary

• Monitors multiple power-supply voltages including fixed and adjustable thresholds
• Provides active-low push-pull reset outputs referenced to VCC1
• Includes a debounced TTL/CMOS-compatible manual-reset input

Applications

• Microprocessor system supervision
• Multi-voltage power supply monitoring
• Portable equipment power management

Procurement Notes

Verify the complete part number suffix for specific threshold configurations and packaging options. Confirm RoHS compliance status and manufacturer lot traceability requirements before ordering. Ensure the selected variant matches the required voltage thresholds and operating temperature range for the target application environment.

Selection Notes

Select this component when simultaneous monitoring of three distinct voltage rails is required. The adjustable monitor input allows flexibility for non-standard voltage levels. Verify that the 100ms minimum reset pulse width meets the system's startup timing requirements. Ensure the SOT-23-6 package fits the PCB layout constraints.

Part Context

This device belongs to the MAX6351–MAX6360 series of dual/triple-voltage microprocessor supervisors. These circuits improve system reliability by replacing discrete components with integrated solutions. The series offers various threshold combinations and package options to suit different design needs while maintaining low supply current consumption.

Replacement Considerations

Check for direct pin-to-pin replacements within the MAX635x series such as MAX6355 or MAX6357 if threshold values differ. Verify functional equivalence regarding output type and reset pulse width before substitution.
