ADM6306D331ARJZ1R7

Supervisors Overview

The ADM6306D331ARJZ1R7 is a supervisory circuit manufactured by Analog Devices Inc., housed in a SOT-23-5 package. It functions as a multi-voltage supervisor with two monitored inputs and features an open-drain or open-collector output type. The device operates within a supply voltage range up to 5.5 V, drawing an operating supply current of 5 uA. Key electrical parameters include an overvoltage threshold of 3.126 V and a reset delay time of 1.6 s. It supports manual reset functionality and is designed for applications requiring precise voltage monitoring in low-power systems.

Supervisors Feature Summary

• Dual-channel voltage supervision capability for monitoring multiple power rails simultaneously
• Open-drain or open-collector output configuration for flexible interfacing with various logic families
• Manual reset input allows for user-initiated system recovery independent of voltage thresholds

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Battery backup switching circuits requiring voltage threshold detection
• Industrial control units needing reliable supervisory signals for microprocessor reset

Supervisors Procurement Notes

Verify the specific suffix '1R7' corresponds to the tape-and-reel packaging format when ordering. Confirm that the open-drain/open-collector output requirement matches the target load impedance. Ensure the 3.126 V overvoltage threshold aligns with the protected circuit's maximum allowable input voltage. Cross-reference the SOT-23-5 footprint dimensions with the PCB layout guidelines provided in the official datasheet to ensure mechanical compatibility.

Supervisors Selection Notes

Select this component when dual-input voltage supervision is required within a compact SOT-23-5 footprint. The low 5 uA operating current makes it suitable for battery-powered applications where standby consumption must be minimized. The manual reset feature provides additional control flexibility compared to auto-reset-only supervisors. Verify that the open-drain output drive capability meets the pull-up requirements of the connected logic interface.

Supervisors Part Context

This part belongs to the ADM6306 series of multi-input programmable reset ICs from Analog Devices. These devices are designed to provide robust supervisory functions for complex digital systems. The series typically offers configurable thresholds and reset timing options to accommodate various application-specific voltage profiles and noise immunity requirements.

Supervisors Replacement Considerations

Check for ADM6306 variants with different suffixes indicating alternative threshold voltages or packaging options. Ensure any substitute maintains the same SOT-23-5 pinout and open-drain output structure. Verify that the replacement part supports the required 5.5 V maximum supply voltage and manual reset functionality.
