Description

The BQ25173-Q1 EVM contains the BQ25173-Q1 IC, LDO TPS7B8133 and support circuits needed operate the evaluation board. Only external power supply is needed for 2.5 and 5 V setting, which corresponds to 1S and 2S. Charge Voltage VREG can be set to 4 values, 2.5V and 5 V with J7 and 7.5V and 10 V with R18 and R17. Charge current is set by R3 (ISET) value from 10 mA to 800 mA. A fix value of 400 mA is selected by JP3.
