Figure 14. Automatic Mode Switching

8.3.2

Soft Start

An implemented soft start mechanism reduces the inrush current. Battery current is smoothed when switching the

charge pump on and also at each switching condition. This precaution reduces electromagnetic radiation significantly.

8.3.3 Unused Charge Pump

If the charge pump is not used, capacitors C4 and C5 (not C2) can be removed. The pins C1_P, C1_N and CPOUT

should be left open and keep register cp_on and cp_auto_on at 0 (default value).
