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).
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).
