MAX6358TZUT

Overview

The MAX6358TZUT+T is a dual-channel voltage supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It monitors two independent power supply rails and asserts an active-low reset signal when voltages fall below specified thresholds. The device features a manual reset input, allowing for system initialization control. It operates within a supply voltage range up to 5.5V and includes a fixed reset delay time of 180ms. The component is housed in a compact SOT-23-6 surface-mount package, suitable for space-constrained designs requiring reliable power management.

Feature Summary

• Dual-channel voltage monitoring with configurable threshold detection
• Active-low open-drain reset output for flexible interfacing
• Manual reset input capability for controlled system initialization
• Integrated watchdog timer functionality for enhanced reliability

Applications

• Portable electronic devices requiring multi-rail power supervision
• Embedded systems needing manual reset control
• Industrial equipment with watchdog timer requirements
• Battery-powered applications with low standby current needs

Procurement Notes

Verify the exact suffix configuration against official datasheets, as variations exist within the MAX6358 family. Confirm RoHS compliance status and lead times directly with authorized distributors or Analog Devices representatives. Check for end-of-life notices or obsolescence warnings before finalizing procurement plans. Ensure packaging specifications match production requirements.

Selection Notes

Select this component when dual-voltage supervision with manual reset and watchdog features is required. Compare threshold voltages against target supply rails to ensure proper triggering. Consider the SOT-23-6 package size constraints and operating temperature range (-40°C to +85°C) for environmental compatibility. Verify that the open-drain output type aligns with downstream logic requirements.

Part Context

Part of the MAX635x series of ultra-low-power supervisors from Maxim Integrated. This family offers various channel counts and feature combinations including watchdog timers and manual resets. The MAX6358 specifically targets applications needing dual-channel monitoring with additional control features compared to simpler single-channel variants.

Replacement Considerations

Check for direct pin-compatible alternatives within the MAX635x family such as MAX6357 or MAX6359 series members. Verify functional equivalence regarding threshold voltages, reset delays, and output types before substitution. Consult Analog Devices replacement guides for officially recommended cross-references.
