DA9070 / DA9231 Fuel Gauge Development Kit

DA9070 Evaluation

The typical application diagram of DA9070 is shown in

DA9070 includes a Buck regulator, a Boost Regulator, 3x LDO/LDSW, and a linear battery charger.

On DA9070 Fuel gauge EVK, each regulator can be evaluated individually. It is recommended to

follow the operation conditions as shown in

and measurement set-up, please refer to
