Battery Chargers Procurement Notes

Verify the specific package variant matches the required footprint, as the component utilizes a 6-USP-B07 (1.8x2) surface mount package. Confirm that the selected termination voltage configuration aligns with the target battery chemistry specifications. Ensure compatibility with the intended operating temperature range of -40°C to 85°C. Cross-reference the manufacturer part number against official distributor catalogs to confirm authenticity and availability status prior to procurement.

Battery Chargers Selection Notes

Select this component when designing circuits for single-cell Li-ion or Li-polymer batteries requiring integrated thermal monitoring. The fixed 4.2V output makes it suitable for standard single-cell applications. Consider the 40mA maximum current limit for low-power devices. The inclusion of reverse current protection simplifies system design by eliminating the need for external blocking diodes in certain configurations.
