Page 2: Introduction
600mA with external resistor on ISET. 1.1 Printed Circuit Board Assembly The BQ25171EVM PCB contains the BQ25171 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. -
Page 3: Test Summary
This section describes the jumpers and connectors on the EVM as well as how to properly connect, setup, and use the BQ25171EVM. Note that the default jumper setting of headers are marked with two dots to indicate the shorting jumper position. This will put the unit into a single cell Li-Ion configuration, 4.2 V at 400 mA. -
