MAX6307UK35D3+

Supervisors Overview

The MAX6307UK35D3+T is a single-input 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 a fixed threshold voltage of 3.5 V. The device provides an active low, push-pull output with a manual reset input capability. It includes a watchdog timer function and has a reset delay time of 225 ms. The component is housed in a SOT-23-5 package and supports surface mount installation. It functions across a temperature range from -40°C to +85°C with a typical operating current of 7 µA.

Supervisors Feature Summary

• Monitors a single power supply rail for undervoltage conditions
• Includes integrated manual reset input for system control
• Features built-in watchdog timer functionality
• Provides active low push-pull reset output signal

Supervisors Applications

• Portable electronic devices requiring low standby current
• Microprocessor systems needing reliable power supervision
• Battery-powered equipment with voltage monitoring needs

Supervisors Procurement Notes

Verify the exact suffix against official documentation, as the provided model lacks the tape-and-reel indicator present in datasheet listings like MAX6307UK35D3L+T. Confirm RoHS compliance status directly with the manufacturer or authorized distributors. Ensure the specific package variant matches design requirements before ordering. Check availability status as distribution may vary by region.

Supervisors Selection Notes

Select this component when a single-channel supervisor with manual reset and watchdog features is required. Compare the 3.5 V threshold against target supply rails to ensure proper triggering. Consider the 7 µA quiescent current for battery life optimization. Verify that the SOT-23-5 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 series of CMOS microprocessor supervisory circuits designed to monitor multiple or single power supplies. These devices assert a reset if monitored supplies fall outside programmed thresholds. The series is characterized by low supply current and small package sizes, making them suitable for portable applications where space and power efficiency are critical.

Supervisors Replacement Considerations

Check for MAX6307UK35D3L+T for identical electrical specifications with potential packaging differences. Review MAX6307UKxxD3+ variants for different threshold voltages if system requirements change. Ensure pinout compatibility when substituting with other MAX630x family members.
