ADM6315-44D3ARTZR7

Supervisors Overview

The ADM6315-44D3ARTZR7 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 4.4V, ensuring accurate detection of power supply levels. It includes a manual reset input for system control and offers a typical reset delay time of 1.57 seconds. The component operates within a maximum supply voltage of 5.5V and is housed in a compact SOT-143-4 surface-mount package.

Supervisors Feature Summary

• Provides reliable supervision of a single voltage rail with a fixed threshold
• Features an open-drain reset output compatible with various logic families
• Includes a manual reset input for active system intervention

Supervisors Applications

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

Supervisors Procurement Notes

Verify the specific suffix ARTZR7 against the manufacturer's current datasheet to confirm tape-and-reel packaging and temperature grade. Confirm availability status as distribution channels may list limited stock or end-of-life conditions. Ensure the 4.4V threshold matches the target application requirements before ordering.

Supervisors Selection Notes

Select this component when a fixed 4.4V threshold is required for voltage supervision. The open-drain output allows flexibility in pull-up voltage selection. Consider the 1.57s reset delay for timing-sensitive applications. Verify that the SOT-143-4 package fits the PCB layout constraints.

Supervisors Part Context

This part belongs to the ADM6315 family of supervisory circuits designed for low-cost, space-constrained applications. The series typically offers fixed thresholds and manual reset capabilities. The specific model indicates a 4.4V threshold variant packaged in SOT-143-4.

Supervisors Replacement Considerations

Check for ADM6315 variants with different threshold voltages if the 4.4V level is not suitable. Verify pinout compatibility with other SOT-143-4 supervisor ICs from Analog Devices or Microchip.
