LP3947ISDX-09/NOPB

Battery Chargers Overview

The LP3947ISDX-09/NOPB is a single-cell lithium-ion battery charger integrated circuit manufactured by Texas Instruments. It features an integrated pass transistor, eliminating the need for external current sensing resistors or Schottky diodes. The device manages charging from USB power sources or AC adapters, supporting fast charge and trickle charge modes. It includes thermal regulation to limit die temperature during high-power operation. The component is housed in a 14-WSON (4x4) package.

Battery Chargers Procurement Notes

Verify the exact part number suffix against official Texas Instruments documentation to confirm package type and temperature range. Ensure compatibility with specific battery chemistry requirements. Cross-reference datasheet revisions for any updates to electrical characteristics or pinout configurations before integration into final designs.

Battery Chargers Selection Notes

Select this component for applications requiring a compact solution for single-cell Li-Ion batteries. The integrated pass transistor reduces external component count. Consider the 14-WSON package size constraints. Verify input voltage ranges match the intended USB or AC adapter source specifications.

Battery Chargers Part Context

This part belongs to the LP3947 family of battery chargers. It is designed specifically for single-cell lithium-ion applications. The 'ISDX' suffix indicates the specific package variant and tape-and-reel packaging configuration. It is distinct from other TI power management ICs lacking integrated pass transistors.

Battery Chargers Replacement Considerations

Consult official Texas Instruments substitution guides for verified alternatives. Generic replacements may lack the integrated pass transistor feature. Ensure substitute parts support the same 14-WSON package and single-cell Li-Ion charging profiles.
