Function
Open load detection (low = on)
Programmable time delay for short circuit (shutdown delay high/
low = 12 ms/1.5 ms
Software inhibit; low = standby, high = normal operation
(data transfer is not affected by standby function because the
digital part is still powered)
Function
Temperature prewarning: high = warning (overtemperature shut-
down see remark below)
Normal operation: high = output is on, low = output is off
Open-load detection: high = open load, low = no open load
(correct load condition is detected if the corresponding output is
switched off)
Normal operation: high = output is on, low = output is off
Open-load detection: high = open load, low = no open load
(correct load condition is detected if the corresponding output is
switched off)

Short circuit detected: set high, when at least one output is
switched off by a short circuit condition
Inhibit: this bit is controlled by software (bit SI in input register)
and hardware inhibit (Pin 17). High = standby, low = normal
operation
