Dear TI Engineers,
I am confused by the Cin and Rin parameters of BQ77915 cell balancing circuit, from the datasheet, they should be 1KR and 0.1uF, however, from the EVM schematics, they are 43R and 1uF,
could you kindly help to suggest which one the right? Thanks.
Hi,
I understand how that can be confusing! These values depend on if you are using the internal cell balancing feature of the chip, or external cell balancing with additional mosfets. We recommend using the internal feature for cell balancing currents less than 50 mA. The electrical characteristics table in the datasheet describes the correct values.
