MAX6356LSUT+

Overview

The MAX6356LSUT+T is a microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It features three monitored voltage inputs with thresholds of 2.93V, 4.63V, and an adjustable setting. The device provides an active-low push-pull reset output referenced to VCC1. It includes a debounced manual reset input and ensures outputs remain valid as long as any input supply exceeds +1.0V. The component operates within a temperature range of -40°C to +85°C and is housed in a surface-mount SOT-23-6 package.

Feature Summary

• Monitors multiple power-supply voltages including preset and adjustable thresholds
• Provides active-low push-pull reset output referenced to VCC1
• Includes debounced TTL/CMOS-compatible manual-reset input
• Maintains valid reset outputs while any input supply remains above +1.0V

Applications

• Monitoring dual or triple voltage supplies in embedded systems
• Ensuring system reliability through precise power-supply supervision
• Providing reset signals for microprocessors and digital logic circuits

Procurement Notes

Verify the exact part number suffix against official manufacturer documentation to confirm pinout, threshold levels, and package type. Ensure compatibility with the target application's voltage requirements and operating temperature range. Confirm RoHS compliance status if required by regulatory standards. Cross-reference datasheet specifications for reset timeout and supply current parameters before integration into the design.

Selection Notes

Select this component when monitoring three distinct voltage rails is necessary. The adjustable threshold allows flexibility for non-standard voltage levels. The push-pull output drives loads directly without requiring external pull-up resistors. Consider the minimum power-on reset pulse width and manual reset functionality for system initialization sequences. Verify that the SOT-23-6 package fits the available PCB space.

Part Context

The MAX6356 belongs to the MAX6351–MAX6360 series of microprocessor supervisory circuits. This family improves system reliability compared to discrete components by integrating multiple reset functions into a single IC. Devices in this series offer various voltage threshold options and are available in 5- and 6-pin SOT23 packages. They operate over the extended temperature range suitable for industrial applications.
