Part Number: BQ2982

Hi team,

We are looking for the battery protection device witch integrated CHG/DSG FET and has ZVCHG Disable function like BQ298215 or 16.

we plan to use the 1s3p Li-ion battery.

Do you have some recommend protection device?

And is there some FET device witch recommend for BQ2982?

Best regards,

Hi Teritama,

I think the BQ2982 family is the best option for the battery you describe. The BQ2980EVM has FETs that work well with this device - it is important to use FETs with low gate leakage since gate leakage will result in higher supply current on the BQ2982 IC.

Best regards,

Matt

Hi Matt,

Thank you for reply.

I understood BQ2982 is best.

In case that choice in integrated FETs product, should we choice from 'Charger Front-End Protection' product ?

Hi Teritama,

We do not have any battery protectors with integrated FETs. The Charger Front-End protectors are a different type of product - these ICs are for the charger, not the battery.

Regards,

Matt
