L99MH98

I would like to know the working principle of the charger bump for MH98, as well as the working principles of CPOUT, CP1, and CP2. Why can the voltage of the bootstrap capacitor reach 11.3V when VDH = 6V? In other words, why can the voltage of CP rea...

Please reply my question regarding L9369 GIO

I am writing because I have a question about the L9369 chip. The second case of above table ( SPI_GIOx_HSCtrl == 0 and SPI_Off_Giox == 1) , Output  is set to HIGH. I'm curious why GIOx Output is HIGH when SPI_GIOx_HSCtrl is 0.  Thank you.
