MAX6357RVUT+T

Overview

The MAX6357RVUT+T is a triple microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors three input supply voltages and asserts active-low reset outputs when any voltage drops below its preset threshold. The device operates with a maximum supply voltage of 5.5V and draws a typical quiescent current of 20µA. It features a manual reset input, a minimum power-on reset pulse width of 100ms, and an operating temperature range from -40°C to +85°C. The component is housed in a compact SOT-23-6 surface-mount package.

Feature Summary

• Monitors multiple power-supply voltages simultaneously to ensure system reliability
• Includes a debounced manual-reset input compatible with TTL/CMOS logic levels
• Provides active-low push-pull reset outputs referenced to specific supply rails

Applications

• Microprocessor (MPU) systems requiring multi-voltage supervision
• Portable battery-powered equipment needing low standby current
• Industrial control units operating within extended temperature ranges

Procurement Notes

Verify the exact voltage thresholds for the RV suffix against the official datasheet before integration. Confirm that the SOT-23-6 package dimensions match your PCB footprint requirements. Ensure the active-low output polarity aligns with your target controller's reset pin configuration. Check for RoHS compliance documentation if required by your manufacturing standards.

Selection Notes

Select this component when simultaneous monitoring of three distinct voltage rails is necessary. It is suitable for designs prioritizing low power consumption during idle states. Consider the fixed threshold options available in the series if programmable settings are not required. Verify that the 100ms minimum reset pulse width meets your system startup timing constraints.

Part Context

This part belongs to the MAX635x family of dual and triple voltage supervisors designed for embedded applications. These circuits replace discrete monitoring components to save board space and improve accuracy. The family offers various threshold combinations and package options to accommodate different system architectures and voltage levels.
