BQ25070: Line regulation

Gustaf Falk Olson58
Prodigy 610 points
Part Number: BQ25070
Other Parts Discussed in Thread: BQ51013B,

Hi,

The Adaptive Communication Limit of the BQ51013B wireless charger drops the output voltage (see section 8.3.11 in the datasheet) when the device is put in current limit. Thus, to use a subsequent battery charger, it needs to have decent line regulation. Would the BQ25070 be able to regulate the output voltage in presence of a quick line drop of 5V to 4.5V or is there any better LiFePo4-charger (with IoMAx=600mA to the battery) to hook up after the BQ51013B ? Could you share a line regulation curve?

Thanks in advance.

Kind regards,

Gustaf
