• Includes comprehensive fault protection mechanisms such as thermal regulation and reverse current blocking

Battery Chargers Applications

• Portable consumer electronics powered by single-cell lithium-ion or lithium-polymer batteries
• USB-powered devices requiring integrated charging and power distribution
• Space-constrained portable applications utilizing AC adapters or USB ports

Battery Chargers Procurement Notes

Verify the specific suffix RGTT corresponds to the tape-and-reel packaging format required for your assembly line. Confirm that the 16-VQFN footprint matches your PCB layout guidelines. Ensure the 4.2V output voltage aligns with your battery cell specifications. Check RoHS compliance status if mandated by your regional regulations. Validate the operating temperature range against your environmental design requirements.

Battery Chargers Selection Notes

Select this component when designing systems that require a compact solution for both charging and power path management. It is suitable for applications where input sources may vary between standard USB ports and non-regulated AC adapters. Consider the 1.5A current limit when sizing external components and thermal dissipation paths. This IC is appropriate for single-cell chemistries requiring precise voltage regulation.
