BQ25960H Evaluation Module
Description
The BQ25960H evaluation module (EVM) is a
complete charger module for evaluating the highly-
integrated BQ25960H switched cap battery charger
in WCSP package for 1-cell Li-Ion and Li-polymer
batteries in a wide range of smartphones and tablets.
The BQ25960HEVM is rated for a maximum input
current of 5.75A and a maximum charge current of
8 A.
The BQ25960HEVM presents a complete fast
charging design. A typical use case is for the
BQ25611D buck charger (U4) to perform pre-charge
and charge termination, while one or both of the
BQ25960H switched cap chargers (U1 and U2)
perform fast charging to achieve the highest possible
efficiency.
