Diagnosis
Various errors as listed in the table “Diagnosis” are detected. Short circuits and overload
result in turning off the output stages after a delay t_dSD and setting the error flag
simultaneously [EF = L]. Changing the inputs to a state where the fault is not detectable
resets the error flag (input toggling) with the exception of short circuit from OUT1 to
OUT2 (load short circuit).
Flag
Open circuit between OUT1 and OUT2
Short circuit from OUT1 to OUT2
Short circuit from OUT1 to GND
Short circuit from OUT2 to GND
Short circuit from OUT1 to V_S
Short circuit from OUT2 to V_S
Overtemperature or undervoltage

IN: 0 = Logic LOW OUT: Z = Output in tristate condition
EF:
1 = Logic HIGH
= V_S /2 due to internal Pull-up/down resistors
L = Output in sink condition
H = Output in source condition
1 = No error
0 = Error
