MAX6315US26D1-T

Supervisors Overview

The MAX6315US26D1-T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in microprocessor and digital systems. It features an active-low, open-drain reset output with a fixed threshold voltage of 2.63V. The device operates within a supply voltage range up to 5.5V and consumes only 5µA of supply current. It includes a manual reset input and provides a reset delay time of 200ms. The accuracy is specified at 1.8%, with an overvoltage threshold of 2.68V. The component supports a maximum power dissipation of 320mW and functions across a temperature range from -40°C to +125°C.

Supervisors Feature Summary

• Provides reliable supervision of power supply voltages for microprocessor systems
• Features an active-low, open-drain reset output compatible with various logic families
• Includes a manual reset input for user-initiated system control

Supervisors Applications

• Microprocessor (µP) power supply monitoring
• Digital system voltage supervision
• Battery-powered equipment power management

Supervisors Procurement Notes

Verify the specific suffix 'D1' against official Analog Devices documentation, as standard listings often use 'D3'. Confirm RoHS compliance status and lead-free designation. Check manufacturer lifecycle status for obsolescence warnings. Ensure the package type matches SOT-143 specifications. Validate thermal performance requirements against the 320mW dissipation limit.

Supervisors Selection Notes

Select this component when a fixed 2.63V threshold is required for single-channel voltage monitoring. Consider the open-drain output configuration for interfacing with different logic levels. Evaluate the 5µA quiescent current for battery-sensitive applications. Ensure the operating temperature range meets the environmental requirements of the target design.

Supervisors Part Context

This part belongs to the MAX6315 series of µP reset circuits manufactured by Maxim Integrated, now part of Analog Devices. The series offers various threshold voltages and package options. The US variant indicates a specific surface-mount package configuration. These circuits are designed to eliminate external components and adjustments while ensuring circuit reliability.

Supervisors Replacement Considerations

Check for direct substitutes within the MAX6315 family with identical thresholds. Verify compatibility with MAX6314 variants if bidirectional output is acceptable. Confirm pinout and package dimensions match for PCB footprint reuse.
