Note 3) IDD3 is the current that consumes constantly at [CPVDD]. This does not include the operation current in Fast
Lockup mode.
Note 4) When both [PDN1] and [PDN2] are ”High”, the total current consumption is equivalent to “IDD2+IDD3”.
Note 5) In the shipment test, the exposed pad on the center of the back of package is connected to ground.
