ADM6315-45D3ARTRL7

Supervisors Overview

The ADM6315-45D3ARTRL7 is a voltage supervisory circuit manufactured by Analog Devices Inc., designed as an open-drain microprocessor supervisor. It operates within a supply voltage range of 2.5 V to 5 V and features a fixed threshold voltage of 4.5 V for monitoring input lines. The device provides a reset delay time of 200 ms to ensure stable power-up conditions. It utilizes an SOT-143-4 surface-mount package, supporting manual reset functionality without integrated watchdog timers or battery backup switches. The maximum operating voltage is rated at 5.5 V, with an accuracy of 1.8% and a typical quiescent current of 5 uA.

Supervisors Feature Summary

• Provides active low open-drain reset output for reliable signal interfacing
• Includes manual reset pin capability for system control flexibility
• Operates with low quiescent current suitable for power-sensitive designs

Supervisors Applications

• Microprocessor power supply monitoring in embedded systems
• Voltage supervision for digital logic circuits
• Reset generation for single-input voltage rails

Supervisors Procurement Notes

Verify component authenticity through authorized distribution channels due to limited availability status. Confirm package integrity and pin alignment upon receipt. Validate datasheet revision compatibility with existing design specifications before integration. Ensure storage conditions meet manufacturer guidelines to prevent moisture damage to the SOT-143-4 package.

Supervisors Selection Notes

Select this component when a fixed 4.5 V threshold is required for voltage supervision. Consider the 200 ms reset delay duration against system startup timing requirements. Evaluate the open-drain output configuration for compatibility with downstream logic levels. Verify that the absence of watchdog functionality aligns with the application's safety needs.

Supervisors Part Context

This part belongs to the ADM6315 family of microprocessor supervisory circuits from Analog Devices. The series offers various threshold voltages and reset delays in compact packages. The specific suffix indicates the 4.5 V threshold and reel packaging format. It serves as a dedicated solution for monitoring single voltage rails in portable and industrial electronics.

Supervisors Replacement Considerations

Cross-reference with ADM6315 variants offering similar 4.5 V thresholds and 200 ms delays. Verify pinout compatibility with the SOT-143-4 footprint. Check if alternative manufacturers provide equivalent open-drain supervisors with matching electrical characteristics.
