11 Power Supply Recommendations

11.1 Requirements for SYS Output

In order to provide an output voltage on SYS, the bq2416xx requires either a power supply between 4.2 V and

6.0 V for USB input on all versions, 4.2 V and 6.0 V for IN input on bq24168 and 4.2 V and 10.0 V on the

remaining versions with at least 100 mA current rating connected to IN or USB OR a single-cell LiIon battery with

voltage > VBATUVLO connected to BAT. The source current rating needs to be at least 2.5 A in order for the

charger's buck converter to provide maximum output power to SYS.

11.2 Requirements for Charging

In order for charging to occur, the source voltage as measured at the IC's USB or IN pins (factoring in cable/trace

losses from the source) must be greater than the VINDPM threshold (but less than the maximum values above)

and the source's current rating must be higher than the buck converter needs to provide the load on SYS. For

charging at a desired charge current of ICHRG, VUSBorINx IUSBorIN x η > VSYS x (ISYS+ ICHRG) where η is the efficiency

estimate from Figure 1 or Figure 2 and VSYS = VBAT when VBAT charges above VMINSYS. The charger limits IUSBorIN

to that input's current limit setting. With ISYS = 0 A, the charger consumes maximum power at the end of CC

mode, when the voltage at the BAT pin is near VBATREG but ICHRG has not started to taper off toward ITERM.
