BQ24120: BQ24120

Michael Zarling

Part Number: BQ24120

Can you tell me what is the result of connecting a battery reversed polarity to the BQ24120?

Hi Michael,

This could result in electrical-over-stress (EOS) damage to the part. The absolute minimum voltage allowed on BAT per the datasheet is -0.3V.

We have an app note on how to protect against this here: https://www.ti.com/lit/an/slva139/slva139.pdf

Best regards,

Nick
