Page 3: Introduction
Variant bq25601 SLUSCK5 BQ25601EVM-877 The bq25601 evaluation module (EVM) is a complete charger module for evaluating an I C-controlled, single NVDC charge using the bq25601 device. This EVM does not include EV2300/EV2400 interface board. To evaluate the EVM, a EV2300/EV2400 interface board must be ordered separately. -
