1.1 Printed Circuit Board Assembly

The BQ25176EVM PCB contains the BQ25176 IC, LDO TPS7B8133 and support circuits. This board contains several jumpers and connectors. S1 (VSET) allows selected output voltages to be programmed. R9 resistor allows a wide range of adjustment of VSET. R22 can be used to change ISET value, fast charge current. R19 can be used to adjust BIAS, battery temp sensor to simulate hot and cold fault.
