Battery Management Procurement Notes

Verify the specific suffix 'DSGR' against official Texas Instruments documentation to confirm tape-and-reel packaging specifications. Ensure compatibility with existing PCB footprints by cross-referencing the WSON-8 mechanical outline drawing. Confirm that the 250 mV output specification aligns with the target application's balancing requirements before finalizing procurement orders.

Battery Management Selection Notes

Select this component when precise single-cell balancing is required for lithium-ion configurations. The low quiescent current makes it suitable for applications prioritizing energy efficiency. Compare the 14 mA output current against load requirements to ensure adequate drive capability. Verify that the 3 V to 20 V operating range covers the system's maximum voltage conditions.

Battery Management Part Context
