MAX6315US29D1-T

Supervisors Overview

The MAX6315US29D1-T is a low-power CMOS microprocessor supervisory circuit designed to monitor power supplies in digital systems. It features an active-low, open-drain reset output and supports manual reset functionality. The device operates within a supply voltage range of 1 V to 5.5 V with a threshold voltage of 2.9 V. It provides a typical reset delay time of 200 ms and maintains accuracy within 1.8%. Operating currents are minimized at 5 uA, ensuring efficient performance across temperatures from -40°C to +125°C in a compact SOT-143-4 package.

Supervisors Feature Summary

• Provides reliable system reset generation through continuous monitoring of the main power supply rail for undervoltage conditions.
• Integrates a manual reset input pin allowing external control over the reset state independent of supply voltage levels.
• Delivers an active-low open-drain output compatible with standard logic interfaces without requiring additional pull-up components.

Supervisors Applications

• Microprocessor (µP) and digital system power supply supervision
• Battery-powered portable devices requiring low quiescent current
• Embedded controllers needing manual reset capability

Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels due to potential availability constraints. Confirm RoHS compliance status and lead-free specifications against current datasheet revisions before integration into production designs.

Supervisors Selection Notes

Select this part when a fixed 2.9 V threshold is required for single-supervision applications. Consider alternative variants if adjustable thresholds, watchdog timers, or push-pull outputs are necessary for specific interface requirements.

Supervisors Part Context
