ADM6315-31D2ARTZRL

Supervisors Overview

The ADM6315-31D2ARTZRL 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 an open-drain reset output. The device provides a fixed reset delay time of 28 ms and includes a manual reset input for system control. It is housed in a compact SOT-143-4 surface-mount package, 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
• Ensures valid reset output down to minimum operating voltage thresholds

Supervisors Applications

• Microprocessor power supply supervision in embedded controllers
• Voltage monitoring for digital logic circuits requiring stable initialization
• Battery-operated devices needing low-power standby management

Supervisors Procurement Notes

Verify the exact suffix ARTZRL against official Analog Devices documentation to confirm tape-and-reel packaging and specific threshold tolerances. Confirm RoHS compliance status and lead-free specifications directly from the manufacturer datasheet before procurement. Ensure the component source is authorized to avoid counterfeit risks given limited availability channels.

Supervisors Selection Notes

Select this component when a fixed 3.1 V threshold with 28 ms delay is required. Compare against MAX6315 variants if different timeout periods or push-pull outputs are needed. Verify that the open-drain output configuration matches the downstream logic interface requirements without additional pull-up components.

Supervisors Part Context

This part belongs to the ADM6315 family of supervisory circuits. It shares the SOT-143-4 footprint with other variants but differs in threshold voltage and delay timing. The series is designed for general-purpose voltage monitoring where precise timing and low power are prioritized over watchdog functionality.

Supervisors Replacement Considerations

MAX6315US30D1+T offers similar supervision with a 3.08 V threshold and 1.4 ms delay. MAX6315US31D3+T provides a 3.08 V threshold with 200 ms delay. Both use SOT-143 packages but differ in electrical timing characteristics.
