ADM6315-45D3ART-RL

Supervisors Overview

The ADM6315-45D3ART-RL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors a single voltage input and provides an open-drain reset output. The device features a fixed threshold voltage of 4.5 V and a manual reset input. It operates within a supply voltage range of 2.7 V to 5.5 V. The component includes a reset timeout period of 28 ms and guarantees valid reset output down to 1 V. It is housed in a 4-lead SOT-143 surface-mount package.

Supervisors Feature Summary

• Provides reliable system reset via open-drain output when supply voltage drops below the specified threshold
• Includes manual reset input for external control of the reset state independent of voltage levels
• Ensures reset signal validity at low supply voltages down to 1 V for robust operation

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset circuits
• Battery-powered device supervision

Supervisors Procurement Notes

Verify the specific suffix ART-RL confirms tape and reel packaging configuration. Confirm the D3 designation aligns with the required 4.5 V threshold voltage for your design. Check current availability status as distribution may vary. Ensure the SOT-143-4 footprint matches your PCB layout requirements before finalizing procurement.

Supervisors Selection Notes

Select this part when a fixed 4.5 V threshold is required for single-supply monitoring. Choose the open-drain output type if interfacing with logic families requiring pull-up resistors. Consider the 28 ms timeout duration for compatibility with target processor startup times. Verify that the manual reset feature meets system control needs without additional components.

Supervisors Part Context

This component belongs to the ADM6315 series of voltage supervisory circuits from Analog Devices. The series offers various threshold options and output configurations in compact packages. The ADM6315-45D3ART-RL specifically targets applications needing a precise 4.5 V trip point with manual reset capability in a small form factor.

Supervisors Replacement Considerations

Compatible substitutes include other ADM6315 variants with matching 4.5 V thresholds and open-drain outputs, such as ADM6315-45D3ARJ-RL, provided the package and electrical characteristics remain identical.
