ADM6315-31D4ARTZR7

Supervisors Overview

The ADM6315-31D4ARTZR7 is a microprocessor 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 output type. The device provides a manual reset function with a fixed reset delay time of 1.57 seconds. It monitors a single input channel and does not include a watchdog timer or battery backup switch. The component is housed in a SOT-143-4 surface-mount package.

Supervisors Feature Summary

• Provides active-low open-drain reset signal for system supervision
• Includes manual reset capability for user-initiated control
• Operates across standard 2.5 V to 5.5 V supply ranges

Supervisors Applications

• Microprocessor power supply monitoring
• Embedded system reset generation
• Portable electronic device power management

Supervisors Procurement Notes

Verify the specific suffix D4ARTZR7 against official Analog Devices documentation to confirm pinout, tolerance, and tape-and-reel specifications. Ensure compatibility with existing PCB footprints and design-in requirements before procurement. Cross-reference datasheet revisions to avoid obsolete variants.

Supervisors Selection Notes

Select this component when a simple, low-pin-count supervisor with manual reset is required. Verify that the 1.57-second delay meets system startup timing constraints. Confirm that the open-drain output interface matches the target microprocessor's reset input requirements without additional pull-up components if already present.

Supervisors Part Context

This part belongs to the ADM6315 family of supervisory circuits from Analog Devices. The family offers various threshold voltages and output configurations in compact packages. The ADM6315 series is designed for cost-sensitive applications requiring reliable power-on reset functionality in space-constrained environments.

Supervisors Replacement Considerations

Check for direct cross-reference part numbers such as MAX6315 variants with identical threshold and package specifications. Verify functional equivalence regarding reset delay and output drive capability before substitution.
