L6924D013TR

Battery Chargers Overview

The L6924D013TR is a fully monolithic battery charger IC dedicated to single-cell Li-Ion and Li-Polymer battery packs. It integrates all power elements, including the power MOSFET, reverse blocking diode, and sense resistor, within a compact 16-VFQFPN (3x3 mm) package. The device supports an operating input voltage range from 2.5 V to 12 V and offers a maximum programmable charging current of 1 A. It features closed-loop thermal control to prevent overheating and provides diagnostic outputs for system monitoring.

Battery Chargers Feature Summary

• Fully integrated solution incorporating power MOSFET, reverse blocking diode, and sense resistor
• Supports both linear mode with voltage-regulated adapters and quasi-pulse mode with current-limited adapters
• Includes closed-loop thermal control to avoid device overheating during operation
• Provides two open collector outputs for diagnostics, LED driving, or microcontroller communication

Battery Chargers Applications

• Handheld equipment
• Digital cameras
• Space-limited applications requiring single-cell Li-Ion/Polymer charging

Battery Chargers Procurement Notes

Verify the specific suffix D013TR corresponds to the 16-VFQFPN 3x3 mm package and tape-and-reel packaging configuration. Confirm that the component meets the required RoHS compliance standards for your manufacturing process. Ensure compatibility with the intended input voltage range of 2.5 V to 12 V. Check for any specific handling requirements associated with the surface-mount installation type.

Battery Chargers Selection Notes

Select this component when space constraints are critical due to its small 3x3 mm footprint. It is suitable for designs requiring flexible charging profiles via programmable pre-charge and fast-charge currents. Consider its capability to operate in quasi-pulse mode if using current-limited power sources to minimize power dissipation. Ensure the application benefits from the integrated thermal protection and diagnostic outputs.

Battery Chargers Part Context

The L6924D013TR belongs to the L6924 series of battery chargers manufactured by STMicroelectronics. This series is designed for efficient management of single-cell lithium-based batteries. The 'D' variant typically denotes specific electrical characteristics or package options within the family, while '013TR' indicates the specific reel quantity and tape packaging format for automated assembly.

Battery Chargers Replacement Considerations

Direct substitutes may include other parts from the L6924 family with compatible pinouts and electrical specifications. Verify that any replacement maintains the same 16-VFQFPN package dimensions and thermal performance. Ensure the alternative device supports the required 1 A charging current and input voltage range.
