MAX6356TWUT+T

Overview

The MAX6356TWUT+T is a dual/triple-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors multiple power-supply voltages to improve system reliability. The device features active-low, push-pull reset outputs and operates within a supply voltage range of 1 V to 5.5 V. Key electrical parameters include threshold voltages of 1.67 V and 3.08 V, with an additional monitor input for triple-voltage supervision. The reset delay time is 180 ms, and the quiescent supply current is 20 µA. It functions over an extended temperature range from -40°C to +85°C.

Feature Summary

• Precision factory-set power-supply reset thresholds for accurate monitoring
• Active-low, debounced manual-reset input compatible with TTL/CMOS logic
• Watchdog timer functionality with specified startup timeout periods
• Low supply current consumption for energy-efficient operation

Applications

• Microprocessor system power management
• Multi-voltage rail supervision in embedded systems
• Industrial control units requiring extended temperature operation
• Battery-powered devices needing low standby current

Procurement Notes

Verify the specific suffix 'TWUT' against the official datasheet to confirm pinout and package configuration. Ensure the required threshold voltages match the application needs, as this variant specifies particular monitoring levels. Confirm RoHS compliance status through the manufacturer's documentation before integration. Check for obsolescence or limited availability notices directly from Analog Devices distributors.

Selection Notes

Select this component when simultaneous monitoring of two or three distinct voltage rails is required. The SOT-23-6 package suits space-constrained designs. Consider the 180 ms reset delay and 20 µA current draw relative to system timing and power budgets. Verify that the active-low output polarity aligns with the target microprocessor reset requirements.
