DIAGNOSTIC
Open Load
output (OUT1:OUT5 ) when the output pin is in the ON state.
Open load detection levels can be chosen by SPI to detect a
standard bulb, a Xenon bulb for OUT2 only, or LEDs (OLLED
bit). Open load for LEDs only is detected during each regular
switch-off state or periodically each t
D[6:0] = 7F)
must be on at least t

Current Sense
done using the current sense (CSNS) pin connected to an
external resistor. The CSNS resistance value is defined in
function to VCC voltage value. It is recommended to use
resistor 500
