ADM6315-45D2ART-RL

Supervisors Overview

The ADM6315-45D2ART-RL is an open-drain microprocessor supervisory circuit manufactured by Analog Devices Inc. It monitors a single voltage input and provides a reset signal when the supply voltage drops below a threshold of 4.5 V. The device features a manual reset input, operates within a supply voltage range up to 5.5 V, and includes a typical reset delay time of 28 ms. It is housed in a compact SOT-143-4 surface-mount package suitable for space-constrained designs.

Supervisors Feature Summary

• Provides reliable system reset via open-drain output when monitored voltage falls below the specified threshold
• Includes a manual reset input pin allowing external control over the reset state independent of supply conditions
• Operates with low quiescent current consumption suitable for battery-powered applications

Supervisors Applications

• Microprocessor power supply monitoring
• Battery-operated electronic systems
• Portable communication devices

Supervisors Procurement Notes

Verify the exact threshold voltage and package variant against the official datasheet before procurement. Confirm availability status as distribution channels may list limited stock or end-of-life statuses. Ensure the ordering suffix matches the required reel quantity and tape specifications for your assembly line.

Supervisors Selection Notes

Select this component when a fixed 4.5 V threshold is required for single-supervision applications. Compare the 28 ms reset delay against system timing requirements. Verify that the open-drain output configuration aligns with the pull-up resistor requirements of the connected microcontroller or logic interface.
