ADM6315-31D1ART-RL

Supervisors Overview

The ADM6315-31D1ART-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 3.08V and a manual reset input for user-initiated resets. It operates within a supply voltage range of 2.5V to 5.5V and includes a typical reset delay time of 140ms. The component is housed in a compact 4-lead SOT-143 surface-mount package, designed for space-constrained applications requiring reliable power supervision.

Supervisors Feature Summary

• Provides active-low open-drain reset signal upon detection of undervoltage conditions
• Includes manual reset input pin allowing external control over the reset state
• Operates with low supply current suitable for battery-powered systems
• Ensures stable reset output during power supply transitions with defined delay

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Battery-operated devices requiring undervoltage protection
• Industrial control circuits needing reliable reset generation
• Communication equipment power management subsystems

Supervisors Procurement Notes

Verify the exact suffix ART-RL indicates reel packaging when ordering. Confirm the threshold voltage code D1 corresponds to 3.08V for your specific design requirements. Check current availability status as distribution may vary. Ensure compatibility with your board's SOT-143 footprint and soldering profile. Validate that the open-drain output configuration matches your system's pull-up requirements.

Supervisors Selection Notes

Select this part when a fixed 3.08V threshold is required for system supervision. Choose the open-drain output if your design requires flexible pull-up voltage selection. Consider the manual reset feature if external reset control is necessary. Verify that the SOT-143 package fits your PCB layout constraints. Ensure the operating temperature range meets your application environment specifications.

Supervisors Part Context

This component belongs to the ADM6315 family of microprocessor supervisors from Analog Devices. The family offers various threshold voltages and output configurations in the same small form factor. The -31D1 variant specifically sets the trip point at 3.08V. Similar parts in the series include different voltage codes and optional watchdog timers or push-pull outputs.

Supervisors Replacement Considerations

Direct substitutes include other ADM6315 variants with matching threshold voltages and output types. Cross-reference with MAX6315 series parts for similar functionality from Maxim Integrated. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement supports the required manual reset feature if needed.
