MAX6315US44D1

Supervisors Overview

The MAX6315US44D1 is a voltage supervisory circuit manufactured by Analog Devices Inc. under the Maxim Integrated brand. It monitors a single input with a threshold voltage of 4.4 V and an overvoltage threshold of 4.48 V. The device features an active low, open-drain output and supports manual reset functionality. It operates within a supply voltage range up to 5.5 V and maintains accuracy of 1.8%. The reset delay time is specified at 200 ms, while the operating supply current is 5 uA. It functions reliably across a temperature range from -40°C to +125°C and is housed in a SOT-143-4 package.

Supervisors Feature Summary

• Provides precise voltage supervision for single-input power rails
• Features manual reset capability for system control
• Delivers active low open-drain reset signal output

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-powered system voltage supervision
• Portable electronic device power management

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and check for obsolescence notices as this series may have limited availability. Ensure the specific suffix matches required electrical parameters before procurement.

Supervisors Selection Notes

Select this component when a fixed 4.4 V threshold is required for single-supervision applications. Consider the open-drain output compatibility with downstream logic levels. Evaluate the 5 uA quiescent current against battery life requirements. Verify that the SOT-143-4 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the MAX6315 family of microprocessor supervisory circuits designed by Maxim Integrated. These devices are engineered to monitor power supplies in embedded systems. The US44 variant specifically targets applications requiring a 4.4 V trip point. The family emphasizes low power consumption and compact packaging for portable electronics.

Supervisors Replacement Considerations
