ADM6306D346ARJZ-R7

Supervisors Overview

The ADM6306D346ARJZ-R7 is a dual voltage supervisor IC from Analog Devices Inc., designed to monitor two independent power supplies. It features a programmable reset delay and an open-drain or open-collector output, suitable for DSP and microprocessor systems. The device operates within a supply voltage range of 1.2V to 5.5V and offers a threshold voltage of 3.46V for the monitored inputs. Packaged in a compact SOT-23-5 surface-mount case, it ensures reliable system reset during brown-out conditions.

Supervisors Feature Summary

• Dual-channel monitoring capability for independent power rails
• Programmable reset delay timer for flexible timing control
• Open-drain/open-collector output configuration for logic compatibility

Supervisors Applications

• Digital signal processor (DSP) system supervision
• Microprocessor-based embedded system reset management
• Multi-supply battery-powered device protection

Supervisors Procurement Notes

Verify the specific suffix ARJZ-R7 against the official Analog Devices datasheet to confirm the package type, temperature grade, and reel quantity. Ensure the design supports open-drain pull-up requirements. Confirm availability status as distribution channels may vary by region.

Supervisors Selection Notes

Select this component when dual-voltage monitoring with programmable timing is required. Compare threshold accuracy and quiescent current against single-channel alternatives if only one rail needs supervision. Verify that the open-drain output aligns with the target system's input logic levels and pull-up resistor constraints.

Supervisors Part Context

This part belongs to the ADM6305/ADM6306 family of supervisory circuits. It shares architectural similarities with other devices in the series but differs in channel count and specific threshold settings. The family targets general-purpose voltage monitoring in portable and industrial electronics requiring robust reset generation.

Supervisors Replacement Considerations

Check for direct pin-compatible substitutes within the ADM63xx series. Verify that alternative parts match the 3.46V threshold and SOT-23-5 package dimensions. Ensure functional equivalence in reset delay programming and output drive capability before substitution.
