MAX6307UK35D3+T

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 of 1.2V to 5.5V and features a fixed reset threshold of 3.5V. The device provides an active-low, push-pull output with a manual reset input and includes a watchdog timer function. It is housed in a compact SOT-23-5 package and supports operation across an industrial temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Integrates a watchdog timer for system fault monitoring alongside voltage supervision
• Features a manual reset input allowing external control over the reset state
• Provides an active-low, push-pull output driver for direct logic interfacing

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Watchdog timer implementation for system reliability
• Portable electronic devices requiring low standby current

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices. Ensure storage conditions adhere to moisture sensitivity level requirements. Validate part markings against official datasheet specifications to prevent counterfeit risks.

Supervisors Selection Notes

Select this component when a single-channel supervisor with integrated watchdog functionality is required. The fixed 3.5V threshold suits standard 3.3V logic systems. Consider the SOT-23-5 package size for space-constrained designs. Verify that the active-low output polarity matches the target microcontroller reset input requirements.

Supervisors Part Context

This part belongs to the MAX6305–MAX6313 family of 5-pin multiple-input programmable reset ICs. These CMOS supervisory circuits are designed to monitor power supplies and assert a reset signal if voltages fall outside programmed thresholds. The family emphasizes low supply current and small package footprints suitable for portable applications.
