Power Supply Controllers, Monitors Procurement Notes

Verify the UC2544N status as discontinued on the manufacturer's official channels before procurement planning. Confirm availability through authorized distributors such as Rochester Electronics, LLC, which currently handles stock distribution. Ensure that the 18-PDIP package dimensions match the target PCB footprint. Validate RoHS3 compliance documentation for regulatory adherence. Cross-reference the DigiKey part number 296-34706-5-ND for accurate ordering specifications.

Power Supply Controllers, Monitors Selection Notes

Select the UC2544N when a dedicated power supervisor is required for inputs between 4.5V and 40V. Consider the 18-PDIP through-hole package for legacy or high-reliability board designs. Evaluate the 7 mA supply current against system power budgets. The -25°C to 85°C operating range suits general industrial environments. Verify that the specific supervision features align with the application's voltage threshold requirements.

Power Supply Controllers, Monitors Part Context

The UC2544N belongs to the UC2544 family of power controllers and supervisors from Texas Instruments. It shares architectural similarities with other devices in the UC series but is distinct in its specific supervision capabilities and 18-pin configuration.
