* Note: Value of capacitor has to be choosen carefully to limit the VS voltage below absolute
maximum ratings in case of an unexpected freewheeling condition (e.g. TSD, POR)
*
** Note: Resistors between µC and L9954LXP are recommended to limit currents
for negative voltage transients at VBAT (e.g. ISO type 1 pulse)
