Mismatch between Source and Sink Currents: [(|Isink|-|Isource|)/{(|Isink|+|Isource|)/2}] × 100 [%]

See “Fig. 4 Charge Pump Characteristics - Voltage vs. Current”: Icp vs. Vcpo:

[{1/2×(|I1|-|I2|)}/{1/2×(|I1|+|I2|)}]×100 [%]

[PDN1]=”High”, [PDN2]=”High” ,

the total current consumption = IDD2 + IDD3 + charge pump setting

In the shipment test, the exposed pad on the center of the back of the package is connected to ground.
