10 Power Supply Recommendations

In order to provide an output voltage on the SYS pins, the bq25600C device requires a power supply between 3.9 V and 14.2 V input with at least 100-mA current rating connected to VBUS and a single-cell Li-Ion battery with voltage > VBATUVLO connected to BAT. The source current rating needs to be at least 3 A in order for the buck converter of the charger to provide maximum output power to SYS.
