MAX6358LSUT

Overview

The MAX6358LSUT+T is a dual-channel voltage supervisor IC manufactured by Analog Devices Inc./Maxim Integrated. It monitors two input supply voltages with preset thresholds of 2.63V and 4.63V. The device features an active-low, open-drain reset output referenced to VCC1. It includes a debounced manual reset input and operates within a supply voltage range up to 5.5V. The component provides a minimum power-on reset pulse width of 100ms and functions reliably across an extended temperature range from -40°C to +85°C.

Feature Summary

• Monitors two independent voltage inputs with factory-set precision thresholds
• Provides an active-low open-drain reset output for system control
• Includes a debounced manual reset input compatible with TTL/CMOS logic

Applications

• Microprocessor (µP) supervisory circuits
• Dual voltage power supply monitoring systems
• Embedded systems requiring multiple voltage supervision

Procurement Notes

Verify the specific suffix 'LSUT' against the manufacturer's official part numbering guide to confirm threshold levels and package type. Confirm RoHS compliance status and check for any product change notices or end-of-life announcements prior to procurement. Ensure the open-drain output configuration matches the target circuit design requirements.

Selection Notes

Select this component when dual voltage supervision is required with low quiescent current consumption. The open-drain output necessitates an external pull-up resistor; ensure the pull-up voltage aligns with the monitored supply rails. Verify that the fixed threshold values of 2.63V and 4.63V meet the specific power rail requirements of the application.

Part Context

This device belongs to the MAX6351–MAX6360 series of microprocessor supervisors designed to improve system reliability. These integrated circuits replace discrete components by offering precise monitoring of multiple power-supply voltages in a compact SOT-23-6 package. The series supports various threshold combinations and output configurations to suit diverse embedded applications.

Replacement Considerations

Check the MAX6358LRUT+T for similar dual-channel functionality, noting it is marked as obsolete. Verify if other variants within the MAX6358 family offer compatible pinouts and electrical characteristics suitable for direct substitution.
