Battery Management Procurement Notes

Verify the specific suffix 'TB' corresponds to the required tape-and-reel packaging format as specified by ABLIC. Confirm that the overcharge threshold (4.250 V) aligns with the target battery chemistry requirements. Ensure the TSSOP-16 package footprint matches the PCB design guidelines provided in the official datasheet. Cross-reference the full part number to confirm RoHS compliance status.

Battery Management Selection Notes

Select this component when designing protection systems for 3S or 4S lithium-based battery architectures. The fixed overcharge threshold of 4.250 V suits standard lithium-ion cells. Consider the ±0.025 V accuracy for applications requiring tight voltage margins. Evaluate the 2.40 V overcurrent detection threshold against the system's maximum allowable discharge current to ensure appropriate protection levels without nuisance tripping.
