Reference Ground for Input Voltage at Sense Input Capacitor between this terminal and Sense Ground determines the current slope dIo/dt during off phase. Low level at this input sets the device after a delay time tdr in the standby mode independent from control input (2nd priority) (in standard applications pin 6 must be left unconnected). High level at this input switches the BU508 off, low level switches the BU508 on. A high level at this input switches the BU508 off independent from all other inputs (1st priority).
