LP3910SQ-AK/NOPB

Power Management - Specialized Overview

The LP3910SQ-AK/NOPB is a specialized Power Management IC (PMIC) designed for hard-drive-based portable applications. Manufactured by Texas Instruments, it operates within a supply voltage range of 2.7 V to 6 V and draws a typical operating supply current of 30 µA. The device supports an output current of 600 mA and functions reliably across an ambient temperature range from -40°C to +85°C. It is housed in a compact 48-pin WQFN package with an exposed pad, suitable for surface-mount technology (SMD/SMT) installation.

Power Management - Specialized Feature Summary

• Integrates programmable system power management with dedicated green and red LED charger status drivers for visual indication.

Power Management - Specialized Applications

• Hard-drive-based portable devices

Power Management - Specialized Procurement Notes

Verify the specific suffix AK against the official Texas Instruments datasheet to confirm pinout and functional compatibility. Ensure the WQFN-48 package dimensions match your PCB footprint design. Confirm RoHS compliance status through the manufacturer's product information page before finalizing procurement specifications.

Power Management - Specialized Selection Notes

Select this component when designing power systems for portable storage devices requiring integrated charger monitoring. The low quiescent current aids in extending battery life. Verify that the 600 mA output capability meets the load requirements of the target application circuitry.

Power Management - Specialized Part Context

This part belongs to the LP3910 series of PMICs from Texas Instruments. It is distinct from other variants like the LP3910SQ-AN/NOPB or LP3910SQ-AP/NOPB primarily by its ordering suffix, which denotes specific package or testing configurations. It serves as a dedicated solution for managing power distribution in mobile hard drive enclosures.

Power Management - Specialized Replacement Considerations

Consult the official TI datasheet for confirmed substitute part numbers. Direct replacements must maintain the WQFN-48 package and compatible electrical characteristics for hard-drive PMIC applications.
