What is the max. possible capacitance values of CCP, CCP1, and CCP2 for the TLE9210x device family?
CCP1 is an external capacitor connected between CPC1N and CPC1P.
CCP2 is an external capacitor connected between CPC2N and CPC2P.
CCP is an external capacitor connected between VS and CP
For CCP1 and CCP2: A capacitance of 220 nF (50V rated) is recommended is is recommended not to exceed 330 nF. The internal charge pump circuit has a certain current capability, and might not be able to fully charge CCP1 and CCP2 during a charge pump cycle, if the capacitance values of CCP1 and CCP2 are too high.
For the buffer capacitor CCP between VCP and VS, 470nF is recommended. A higher value such as 1 µF is possible for lower voltage ripple at VCP. If the capacitance value is bigger, it takes longer time for the internal charge pump circuit to overcome the CP undervoltage.
