Charge pump
The L9779WD charge pump could be active if the battery supply voltage is smaller than
12 V or be permanently active by setting the capful bit enable or disable. Charge pump
provides a permanent voltage of at least 5 V above Ubat when Ubat is higher than 6 V with
an external load current at pin CP of 50 µA additional to the L9779WD internal loads.
Once Ubat overvoltage is detected (VB_OV_th > 28 V), the charge pump will be switched
off automatically no matter the cp_off bit status.
