Status signal valid after the time delay shown in the timing diagrams
Parallel switching of channel 1 and 2 is easily possible by connecting the inputs and outputs in parallel. The
status outputs ST1 and ST2 have to be configured as a ’Wired OR’ function with a single pull-up resistor.

Leadframe (Vbb) is connected to pin 1,10,11,12,15,16,19,20
External RGND optional; two resistors RGND1, RGND2 = 150 Ω or a single resistor RGND = 75 Ω for reverse
battery protection up to the max. operating voltage.
13) With external resistor between output and Vbb
14) An external short of output to Vbb in the off state causes an internal current from output to ground. If RGND is
used, an offset voltage at the GND and ST pins will occur and the VST low signal may be errorious.
15) Low resistance to Vbb may be detected by no-load-detection
