MAX6356UVUT

Overview

The MAX6356UVUT+T is a dual/triple-voltage microprocessor supervisor in a SOT-23-6 package. It monitors three supply rails with thresholds of 2.93V, 4.63V, and an adjustable input. The device features active-low push-pull outputs referenced to VCC1, a debounced manual reset input, and a minimum 100ms power-on reset pulse width. It operates from -40°C to +85°C with a maximum supply voltage of 5.5V.

Feature Summary

• Monitors multiple power-supply voltages including two fixed thresholds and one adjustable input
• Provides active-low push-pull reset outputs referenced to the primary supply rail
• Includes a debounced manual-reset input compatible with TTL/CMOS logic levels

Applications

• Multi-rail embedded system power supervision
• Microprocessor reset circuitry for industrial controllers
• Portable equipment power management

Procurement Notes

Verify the complete part number suffix, as variations such as +T indicate tape-and-reel packaging. Confirm the specific voltage threshold configuration matches the design requirements, as the MAX6356 series offers multiple factory-set options. Ensure the SOT-23-6 footprint aligns with the PCB layout specifications before finalizing procurement orders.

Selection Notes

Select this component when simultaneous monitoring of three distinct voltage rails is required within a compact surface-mount package. The adjustable monitor input allows flexibility for non-standard voltage levels. Verify that the push-pull output drive capability meets the downstream load requirements compared to open-drain alternatives.

Part Context

This device belongs to the MAX635x family of microprocessor supervisors designed to improve system reliability. Unlike single-channel detectors, this series integrates multiple comparators into a single IC, reducing board space and component count while ensuring synchronized reset assertion across all monitored supplies.

Replacement Considerations

Direct replacements include other MAX6356 variants with identical pinouts but different voltage thresholds, such as MAX6356LSUT+T or MAX6356MWUT+T. Cross-family substitutes like the MAX6357 offer similar functionality but may differ in output configuration or additional features.
