Battery Chargers Procurement Notes

Verify the specific suffix D14 against official Torex documentation to confirm pinout and functional configuration. Ensure the ordering quantity aligns with the manufacturer's standard packaging requirements. Confirm RoHS compliance status through the latest datasheet revision before finalizing procurement specifications.

Battery Chargers Selection Notes

Select this component when a low-profile USP-6EL package is required for space-constrained designs. The 280 mA output current suits applications with moderate battery capacity requirements. Consider the 4.5 V minimum input voltage constraint to ensure adequate headroom for the target power source.
