MAX6359MSUT+T

Overview

The MAX6359MSUT+T is a dual-voltage microprocessor supervisory circuit manufactured by Analog Devices Inc./Maxim Integrated. It monitors two input supply voltages and asserts active-low, push-pull reset outputs when any voltage drops below its preset threshold. The device operates within a supply range of 1.2V to 5.5V and features a manual reset input with debouncing. It includes a watchdog timer with a 46.4s startup timeout and a 2.9s normal timeout. The component is housed in a 6-pin SOT-23 package and functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Monitors multiple power-supply voltages with precision factory-set thresholds
• Includes a watchdog timer for system reliability
• Features a debounced manual-reset input compatible with TTL/CMOS logic

Applications

• Microprocessor system power monitoring
• Embedded controller voltage supervision
• Industrial control board reset management

Procurement Notes

Verify the specific suffix 'MSUT' against the official datasheet to confirm pinout and electrical characteristics match your design requirements. Ensure the manufacturer designation aligns with current Analog Devices or Maxim Integrated sourcing channels. Confirm RoHS compliance status through official documentation before finalizing procurement plans.

Selection Notes

Select this component when simultaneous monitoring of two distinct voltage rails is required within a compact surface-mount footprint. The integrated watchdog timer simplifies firmware design by providing hardware-based fault detection. Verify that the available threshold voltages meet the specific rail requirements of the target application without external resistor dividers.

Part Context

This part belongs to the MAX6351–MAX6360 family of microprocessor supervisors designed to improve system accuracy compared to discrete solutions. These devices assert reset outputs if any monitored supply falls below its threshold, provided at least one supply remains above 1.0V. The series offers various threshold levels and packaging options to suit diverse embedded applications.

Replacement Considerations

Consult the official datasheet for confirmed substitute part numbers within the MAX635x family. Verify compatibility regarding threshold voltages, output drive capability, and package dimensions before implementing any alternative components.
