Function
Device Output
Supply Voltage
Input voltage that determines output current.
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).
