ADM6315-46D3ART-RL

Supervisors Overview

The ADM6315-46D3ART-RL 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 a fixed reset threshold voltage of 4.6 V. The device provides an open-drain output and includes a manual reset input for system control. It utilizes a 4-lead SOT-143 surface-mount package and offers a typical reset delay time of 280 ms. This component is designed for reliable voltage monitoring in embedded applications.

Supervisors Feature Summary

• Provides active-low open-drain reset signal generation based on monitored supply voltage levels
• Includes a dedicated manual reset input pin allowing external assertion of the reset state
• Operates with low quiescent current consumption suitable for battery-powered systems
• Delivers precise voltage supervision with guaranteed accuracy across specified temperature ranges

Supervisors Applications

• Microprocessor power supply monitoring in industrial control systems
• Voltage supervision for embedded controllers in consumer electronics
• Reset circuitry for field-programmable gate array (FPGA) power sequencing
• Battery-operated devices requiring reliable brown-out detection

Supervisors Procurement Notes

Verify the specific suffix ART-RL indicates tape-and-reel packaging configuration when sourcing. Confirm the D3 variant corresponds to the 4.6 V threshold specification against official datasheets. Ensure compatibility with SOT-143-4 footprint requirements during procurement planning. Check for RoHS compliance status as per manufacturer documentation.

Supervisors Selection Notes

Select this component when a fixed 4.6 V threshold is required for single-supply monitoring. The open-drain output allows flexible interfacing with various logic families through pull-up resistor selection. Consider the 280 ms reset delay for timing-sensitive applications. Verify that the manual reset feature aligns with system recovery strategies.

Supervisors Part Context

This part belongs to the ADM6315 family of open-drain microprocessor supervisors from Analog Devices. The family shares common architectural features including manual reset capability and low power operation. Variants differ primarily in reset threshold voltages and packaging options. The ADM6315 series serves as a standard solution for basic voltage supervision tasks.

Supervisors Replacement Considerations

Cross-reference with MAX6315US46D3+T for similar functionality from Maxim Integrated. MIC6315-46D3UYTR from Microchip offers comparable specifications in a different package. Verify pinout compatibility and electrical parameters before substitution.
