MAX6307UK29D3-T

Supervisors Overview

The MAX6307UK29D3-T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It asserts a system reset if any monitored supply falls outside the programmed threshold, making it suitable for monitoring both 5V and 3.3V in personal computer systems. The device features an active-low open-drain output, manual reset input, and operates within a maximum supply voltage of 5.5V. It draws 8µA of supply current and functions between -40°C and +85°C.

Supervisors Feature Summary

• Monitors more than one power supply and asserts reset if any fall outside thresholds
• Includes manual reset input for system control
• Immune to short VCC transients on monitored supplies
• Operates with low supply current suitable for portable applications

Supervisors Applications

• Personal computer systems
• Portable computers
• Controllers
• Intelligent instruments
• Multivoltage systems (e.g., 3V/5V, 5V/12V)

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and specific lot traceability before integration. Ensure storage conditions align with moisture sensitivity level requirements to maintain package integrity and electrical performance during assembly.

Supervisors Selection Notes

Select this part when simultaneous monitoring of multiple voltage rails is required. Verify that the factory-set reset threshold matches the target supply voltage. Consider the SOT-23-5 package size for space-constrained designs. Ensure the operating temperature range meets the environmental demands of the final application.

Supervisors Part Context

Part of the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs from Analog Devices / Maxim Integrated. These devices are specifically engineered to ignore fast transients on monitored supplies while providing precise reset timing.

Supervisors Replacement Considerations

Cross-reference with other MAX630x series variants such as MAX6306UK29D3-T or MAX6307UK31D3+T for similar functionality. Verify pinout compatibility and reset threshold specifications before substitution.
