L6611D

Power Supply Controllers, Monitors Overview

The L6611D is a programmable auxiliary controller manufactured by STMicroelectronics, designed for housekeeping power management applications. It operates within a supply voltage range of 4.2V to 7V and draws a typical supply current of 5 mA. The component is housed in a 20-SOIC package with a width of 7.50mm (0.295 inches), suitable for surface mount installation. It supports an extended operating temperature range from 0°C to 125°C TJ. This device functions as a dedicated power controller, offering programmability features for auxiliary control tasks in electronic systems.

Power Supply Controllers, Monitors Procurement Notes

Verify component status carefully as the L6611DTR variant is listed as obsolete or end-of-life by major distributors. Confirm availability through authorized channels or secondary markets if production continuity is required. Check RoHS compliance status, as indicated data suggests non-compliance. Ensure the specific suffix matches design requirements, noting that packaging variations exist but function remains consistent per datasheet specifications.

Power Supply Controllers, Monitors Selection Notes

Select this component when a dedicated programmable auxiliary controller is needed for low-voltage housekeeping rails. The 20-SOIC package requires adequate PCB space consideration. Verify thermal management capabilities for the 0°C to 125°C operating range. Consider the 5 mA supply current impact on overall system efficiency. Evaluate compatibility with existing power sequencing requirements before integration.

Power Supply Controllers, Monitors Part Context

The L6611 series belongs to STMicroelectronics' portfolio of power management integrated circuits. It complements other PMIC solutions by providing specialized auxiliary control rather than primary regulation. The family includes variants like L6611DTR, catering to different packaging and volume needs. It serves niche applications requiring precise, programmable power management logic distinct from standard DC-DC controllers.

Power Supply Controllers, Monitors Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation. The L6611DTR variant is explicitly marked as obsolete. Designers should consult official STMicroelectronics resources for potential obsolescence management strategies or alternative component recommendations.
