MAX6309UK27D1

Supervisors Overview

The MAX6309UK27D1+T is a CMOS microprocessor supervisory circuit designed to monitor multiple power supplies. It features two monitored inputs with factory-programmed reset threshold voltages of 2.741 V and 5 V. The device provides an active low, push-pull output and includes a manual reset input. It operates within a supply voltage range up to 5.5 V and has a reset delay time of 1.4 ms. The component draws 8 µA of supply current and functions in temperatures from 0°C to +70°C. It is housed in a compact SOT-23-5 package.

Supervisors Feature Summary

• Monitors multiple power supplies and asserts system reset if any fall outside programmed thresholds
• Designed to ignore fast transients on monitored supplies
• Includes manual reset input for user-initiated control

Supervisors Applications

• Monitoring 5V and 3.3V supplies in personal computer systems
• Portable applications requiring low supply current
• Microprocessor supervisory circuits

Supervisors Procurement Notes

Verify the RoHS compliance status and lead-free designation when sourcing this component. Confirm the specific suffix indicates the correct threshold voltage configuration. Check availability as distribution may be limited or subject to factory special orders. Ensure the package type matches the design requirements.

Supervisors Selection Notes

Select this part for applications requiring dual-input monitoring with fixed thresholds. Consider the 8 µA supply current for battery-powered designs. Verify that the SOT-23-5 package fits the board layout. Ensure the operating temperature range meets the environmental conditions.

Supervisors Part Context

This component belongs to the MAX6305–MAX6313 series of 5-pin, multiple-input, programmable reset ICs. These devices are optimized for monitoring more than one power supply simultaneously. The series is characterized by low supply current and small package size, making it suitable for space-constrained portable electronics.
