18 - 70

The charge pump mode switching can be done manually or automatically with the following possible software

settings:

Automatic up all modes allowed (1:1, 1:1.5, 1:2)

−

Start with 1:1 mode

−

Switch up automatically 1:1 to 1:1.5 to 1:2

Automatic up, but only 1:1 and 1:1.5 allowed

−

Start with 1:1 mode

−

Switch up automatically only from 1:1 to 1:1.5 mode; 1:2 mode is not used

Manual

−

Set modes 1:1, 1:1.5, 1:2 by software

µ F

Ceramic low-ESR capacitor between

pins CP_OUT and VSS, pins VBAT

and VBAT2 (in parallel) and VSS.

Use nominal 2.2µF or 4.7µF

capacitors (size 0603)

Note:

1.) The connections of the external capacitors C5, C6, C7 and C8 should be kept as short as possible.

2.) The maximum voltage on the flying capacitors C6 and C7 is VBAT
