MAX6315US30D1+T

Supervisors Overview

The MAX6315US30D1+T is a low-power CMOS microprocessor supervisory circuit manufactured by Analog Devices Inc. (Maxim Integrated). It operates within a supply voltage range of 1V to 5.5V and monitors a single input channel with a fixed threshold voltage of 3V. The device features an active-low, open-drain output and includes a manual reset input. Key electrical parameters include a reset delay time of 1.4ms, an operating supply current of 5µA, and accuracy of 1.8%. It functions reliably across a temperature range of -40°C to +125°C.

Supervisors Feature Summary

• Provides system reset supervision for microprocessors and digital systems by monitoring power supply voltages.
• Features an active-low, open-drain RESET output compatible with various logic families.
• Includes a manual reset input pin allowing external control over the reset state.
• Designed for low-power applications with minimal operating supply current consumption.

Supervisors Applications

• Microprocessor (µP) reset circuits in embedded systems
• Power supply monitoring in portable electronic devices
• Digital system supervision requiring manual reset capability

Supervisors Procurement Notes

Verify the component authenticity through official Analog Devices channels or authorized distributors. Confirm the presence of the '+' suffix indicating lead-free compliance and RoHS adherence. Ensure the SOT-143-4 package matches your PCB footprint requirements. Check for any specific handling instructions regarding moisture sensitivity level 1 during storage and assembly processes.

Supervisors Selection Notes

Select this component when a fixed 3V threshold is required for single-supply monitoring. It is suitable for designs needing manual reset functionality alongside automatic power-on reset. Consider the open-drain output configuration for interfacing with different voltage levels. Evaluate the 5µA current consumption against battery life requirements for portable applications.

Supervisors Part Context

This part belongs to the MAX6315 series of uP reset circuits from Maxim Integrated. The series offers various fixed threshold voltages and package options. The 'US' designation indicates the SOT-143 package, while '30' specifies the 3.0V threshold. The '+T' suffix denotes tape-and-reel packaging and lead-free construction.

Supervisors Replacement Considerations

Direct substitutes within the same series include MAX6315USxxD1+T variants with different threshold voltages. Cross-reference with other Maxim Integrated supervisory circuits offering similar open-drain outputs and manual reset features if exact threshold matching is not critical.
