ADM6348-40ARTZ-R7

Supervisors Overview

The ADM6348-40ARTZ-R7 is an ultralow power microprocessor reset circuit manufactured by Analog Devices Inc. It operates within a supply voltage range up to 5.5 V and features a fixed threshold voltage of 4.0 V. The device provides an active-low open-drain output with a reset delay time of 185 ms. It consumes only 500 nA of supply current and functions reliably across a temperature range from -40°C to +85°C. Packaged in a compact SOT-23-3 surface-mount case, this component supports single-input voltage monitoring without manual reset or watchdog timer capabilities.

Supervisors Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm pinout and electrical characteristics. Confirm lifecycle status as obsolete before finalizing procurement plans. Ensure compatibility with existing PCB footprints and thermal requirements. Check for RoHS compliance details in the specific datasheet revision. Validate that the open-drain output matches the target system logic levels.

Supervisors Selection Notes

Select this component when a fixed 4.0 V threshold is required for voltage supervision. Consider the 185 ms reset delay for timing-sensitive applications. Evaluate the 500 nA quiescent current against total system power budgets. Ensure the open-drain output can interface correctly with the downstream logic. Verify that the SOT-23-3 package fits the available board space.

Supervisors Part Context

This component belongs to the ADM6348 series of ultralow power reset circuits. The series offers various fixed threshold voltages to accommodate different supply rails. These devices are designed for simple, cost-effective power supervision in embedded systems. The family shares common packaging and low-power characteristics while differing in trip points.

Supervisors Replacement Considerations

Check Analog Devices ordering guides for alternative ADM6348 variants with different threshold voltages. Verify functional equivalence with other ultralow power supervisors if sourcing new components. Ensure substitute parts maintain the same output type and package dimensions.
