• Supports USB interface connectivity for charging applications

Battery Chargers Applications

• Single-cell lithium-ion battery charging systems
• Single-cell lithium-polymer battery charging systems
• USB-powered portable electronic devices

Battery Chargers Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix DR-G matches required packaging specifications. Check for end-of-life status as discontinuation notifications may affect long-term availability. Ensure compliance with RoHS3 and REACH regulations relevant to your region. Validate package dimensions against PCB footprint requirements prior to procurement.

Battery Chargers Selection Notes

Select this component for applications requiring a compact solution for single-cell Li-ion or Li-Po batteries. The fixed 4.45V output suits standard 3.7V nominal cells. Consider the 385mA max current limit relative to battery capacity. The 10-USPB package offers a small form factor suitable for space-constrained designs. Verify thermal dissipation capabilities given the 1.2W power dissipation rating.
