BQ2022A: Is the BQ2022A truly a drop-in replacement for the Maxim DS2502+

Part Number: BQ2022A

Can anyone confirm if the BQ2022A is truly a drop-in replacement for the Maxim DS2502+?

We are upgrading over 10k buses and each of these uses a Maxim DS2502+ but they are hard to obtain.  Researching on the web suggests that they are “drop in replacements” but are they software compatible as well? i.e. can we replace a Maxim DS2502+ in an existing system with software that already exists/cannot be changed .. and it will work?

  • Hi Jamie,

    The pinouts are the same and the devices have similar functionalities, I am not sure the same software can work on both devices. Please read the communication guidelines in our BQ2022A datasheet to ensure proper functionality. 

    Thanks,
