ADM6315-46D4ART-RL

Supervisors Overview

The ADM6315-46D4ART-RL is a microprocessor supervisory circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.5 V to 5 V and features a fixed threshold voltage of 4.63 V. The device provides an open-drain reset output with a manual reset input capability. It utilizes a 4-lead SOT-143 surface-mount package. Key electrical parameters include a maximum supply voltage of 5.5 V, a reset delay time of 1.57 s, and a typical operating current of 5 µA. The component supports single-input monitoring without integrated watchdog or battery backup switching functions.

Supervisors Feature Summary

• Provides active-low open-drain reset signal generation for monitored power rails
• Includes manual reset input pin allowing external control over the reset state
• Designed for low-power applications with minimal quiescent current consumption
• Utilizes compact four-lead SOT-143 surface-mount packaging for space-constrained designs

Supervisors Applications

• Microprocessor system power supervision

Supervisors Procurement Notes

Verify exact availability status through official Analog Devices channels or authorized distributors, as supply conditions may vary. Confirm that the ordering suffix matches the required threshold voltage and package variant. Ensure compliance with RoHS directives if applicable to your manufacturing region. Cross-reference the specific date code and lot traceability requirements with your quality assurance standards before finalizing procurement orders.

Supervisors Selection Notes

Select this component when a fixed 4.63 V threshold is required for systems operating between 2.5 V and 5 V. The open-drain output allows flexibility in interfacing with various logic families by enabling external pull-up resistors. Consider the 1.57 s reset delay duration to ensure compatibility with target processor startup sequences. Verify that the manual reset feature aligns with system recovery requirements.

Supervisors Part Context

This part belongs to the ADM6315 family of supervisory circuits from Analog Devices. The series offers various fixed threshold voltages and output configurations to suit different voltage rails. The -46D4 suffix indicates the specific 4.63 V threshold and package type. These devices are designed to replace older discrete supervisor solutions with integrated, reliable performance in compact form factors.

Supervisors Replacement Considerations

Direct replacements include other ADM6315 variants with compatible thresholds such as ADM6315-46D1ARTRL7. Verify pinout compatibility and electrical specifications against the original design requirements before substitution.
