Other Parts Discussed in Thread: BQ51050B
according to the datasheet, its says as below.
"The AD pin will be tied to the external USB power source to allow for an external source to power the system. AD_EN is tied to the gate of Q1 (CSD75205W1015). This allows the bq51050B to sense when power is applied to the AD pin. The EN2 pin controls whether the wired source will be enabled or not. EN2 is tied to the system host to allow it to control the use of the USB power. If wired power is enabled and present, the AD pin will disable the BAT output and then enable Q1 through the AD_EN pin. An external charger is required to take control of the battery charging."
does this part charge the circuit using USB?
