MAX6308UK00D3+T

Supervisors Overview

The MAX6308UK00D3+T is a dual-channel supervisory circuit designed to monitor multiple power supplies. It operates within a supply voltage range of 1V to 5.5V and features a push-pull output stage. The device provides two independent reset thresholds, allowing for precise monitoring of distinct voltage rails. It includes a fixed timeout period for power-on reset generation and ensures valid reset signals down to 1V. The component is housed in a compact SOT-23-5 package and consumes low quiescent current, making it suitable for space-constrained portable applications.

Supervisors Feature Summary

• Dual-channel architecture for simultaneous monitoring of separate power rails
• Push-pull output configuration for robust drive capability
• Immunity to short transients on monitored supply lines
• Guaranteed reset validity down to 1V supply voltage

Supervisors Applications

• Portable computer systems requiring multi-voltage supervision
• Battery-powered devices with strict power management needs
• Embedded systems monitoring critical logic and I/O voltages
• Industrial control units requiring reliable power fault detection

Supervisors Procurement Notes

Verify the suffix 'T' indicates tape-and-reel packaging when ordering. Confirm the '+T' designation aligns with lead-free compliance requirements for your assembly process. Ensure the specific threshold voltage matches your design needs, as this variant has factory-programmed settings. Check for obsolete status warnings associated with similar suffixes like '-T' versus '+T'. Validate that the SOT-23-5 footprint matches your PCB layout constraints before finalizing procurement.

Supervisors Selection Notes

Select this component when dual independent voltage monitoring is required in a minimal footprint. It is appropriate for designs needing immunity to transient glitches without external filtering components. Choose this part if a push-pull output is preferred over open-drain configurations for faster switching speeds. Consider this IC for applications where low standby current is critical for battery life extension.

Supervisors Part Context

This device belongs to the MAX6305–MAX6313 family of CMOS microprocessor supervisory circuits. These parts are engineered to monitor more than one power supply, ideal for systems using both 5V and 3.3V rails. The family shares common features such as small SOT-23-5 packaging and low supply current consumption. Variants differ primarily in the number of monitored channels and their specific factory-set reset thresholds.

Supervisors Replacement Considerations

The MAX6308UK00D3-T is listed as obsolete. Verify compatibility with other MAX6308 variants or the broader MAX6305–MAX6313 series. Ensure substitute parts maintain the same dual-channel functionality and SOT-23-5 package. Cross-reference threshold voltages carefully, as they vary across the family. Confirm that any replacement supports the required push-pull output type.
