MAX6358LTUT

Overview

The MAX6358LTUT+T is a dual-channel voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It operates within a supply voltage range up to 5.5 V and features two monitored inputs with threshold voltages of 3.08 V and 4.63 V. The device provides an active low, open-drain reset output with a manual reset capability and includes a watchdog timer function. It offers a reset delay time of 180 ms and maintains accuracy within 1.5%. Designed for surface-mount installation in a SOT-23-6 package, it supports an operating temperature range from -40°C to +85°C.

Feature Summary

• Dual-channel voltage monitoring with configurable thresholds
• Integrated watchdog timer for system reliability
• Manual reset input capability
• Active low open-drain reset output

Applications

• Microprocessor power supply supervision
• Embedded system voltage monitoring
• Industrial control board protection
• Consumer electronics power management

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential counterfeit risks. Confirm RoHS compliance status and specific lot traceability requirements before procurement. Check current lifecycle status as some variants may be discontinued. Ensure packaging specifications match production line requirements. Validate electrical parameters against latest datasheet revisions prior to final ordering decisions.

Selection Notes

Select this component when dual-voltage supervision with watchdog functionality is required in compact designs. Consider the SOT-23-6 package size constraints and open-drain output compatibility with downstream logic levels. Evaluate threshold voltage requirements against target supply rails. Assess thermal performance within the specified operating temperature range. Verify manual reset integration needs and watchdog timeout configurations for system stability.

Part Context

This part belongs to the MAX635x series of voltage supervisors designed for microprocessor applications. It shares functional similarities with other members like MAX6359LTUT+T but differs in output type and channel configuration. The series emphasizes low power consumption and high accuracy for reliable system monitoring in portable and industrial devices.

Replacement Considerations

MAX6359LTUT+T offers similar dual-channel monitoring but features push-pull output instead of open-drain. MAX6358LRUT+T provides identical electrical characteristics and pinout compatibility, serving as a direct functional substitute. Verify output stage requirements when selecting alternatives.
