BQ25895: Device Revision

Nicolas Venturo
Intellectual 810 points
Part Number: BQ25895

Hello,

On REG14 of the BQ25895 ( page 49), it is stated that the 'Device Revision' field (bits 1 and 0) reads 0b01. However, when reading this value on my device, I'm getting a value of 0b10.

What gives? Is it a different version? Is there an errata somewhere with the changes? What versions are available?

Thanks

    Nicolas,

    The device you have should be bq25895M with top marking BQ25895M. For more information, please visit www.ti.com/.../BQ25895M.
    The differences of bq25895M and bq25895 are:
    - adds REG03[0] to select the minimum battery voltage to exit boost
    - adds REG0A[3] for boost PFM mode option
    - REG02[3] High voltage handshaking is disabled by default
    - the TQON_RST is 16 seconds min and 23 seconds max
    - REG14[10]=10

    Best regards,
    Eric
