ADBMS6815 vs LTC6811-1 difference

Hello everybody,

so the ADBMS6815 is pretty new. Is it like the successor to the LTC6811-1 or are there more fundamental differences?

  • It is the successor to LTC6811-1, but is somewhat different in that it is built around using the internal switches for balancing rather than external MOSFETs.  External switches are still supported on ADBMS6815, but not needed in many cases due to 300mA balancing with the internal switches.  Other specifications are improved as well.  ADBMS6815 also has a variant, ADBMS6815M, that supports low power cell monitoring (LPCM) for cell and temperature monitoring in key-off state.
