ADM6315-31D4ART-RL

Supervisors Overview

The ADM6315-31D4ART-RL is a single-channel voltage supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5 V to 5.5 V and features an open-drain reset output with a fixed threshold voltage of 3.08 V. The device includes a manual reset input and provides a reset delay time of 1.57 seconds. Packaged in a compact SOT-143-4 surface-mount format, it is designed for monitoring power supplies in microprocessor systems without integrated watchdog timers or battery backup switching capabilities.

Supervisors Feature Summary

• Provides active-low open-drain reset signal generation based on monitored supply voltage levels
• Includes dedicated manual reset input pin for system-initiated reset control
• Operates across a wide industrial temperature range from -40°C to +125°C
• Delivers high accuracy voltage supervision with low quiescent current consumption

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Battery-powered devices requiring reliable voltage supervision
• Industrial control systems operating in extreme temperatures

Supervisors Procurement Notes

Verify the complete part number including suffix ART-RL for reel packaging configuration. Confirm the specific threshold voltage variant matches design requirements as the D4 suffix indicates 3.08 V. Check manufacturer documentation for latest revision status and RoHS compliance details before procurement integration.

Supervisors Selection Notes

Select this component when a fixed 3.08 V threshold is required for 3.3 V logic systems. The open-drain output allows flexible pull-up voltage selection. Ensure manual reset functionality meets system requirements. Verify SOT-143-4 package compatibility with PCB layout constraints and thermal management needs.

Supervisors Part Context
