Monitoring Functions Diagnostics
pins open drain outputs must externally connected pull-up resistors normal conditions, signals default high. case error, pins pulled low. There different error conditions that could flag fault condition:
5.3.1.1
Overcurrent
Output shorted Ground: output transistor turned current rises above shutdown threshold longer than shutdown delay time td_SD, output transistor turned corresponding diagnosis set. Within this delay time, current limited shown Figure Changing INHIBIT input resets error flag. Also power down event will reset Error Flag. Output short same behavior short GND. Short across load: same behavior short GND.
5.3.1.2
Open load
current through side transistor lower than reference current IOLD ON-state longer than open-load detection delay time td_OLD, open-load error flag set. output will remain Once output current increases Iload IOLD, Error Flag will reset automatically after td_OLD filter time (Figure 15).
5.3.1.3
Over voltage over temperature
Over voltage: voltages below undervoltage switch threshold (VUVOFF) above overvoltage switch threshold (VOVOFF), output stages will switched OFF. Error Flag however only signals overvoltage switch case (Figure switching hysteresis implemented both thresholds allow autorecovery mode supply voltage back within operational range. Over Temperature: junction temperature higher than thermal shutdown temperature TjSD (typ. 175°C) device enters thermal shutdown which turns-Off four output stages simultaneously corresponding Error Flags with delay. After cooling down thermal switch-on junction temp TjSO device will auto restart. thermal toggle behavior observed (the Error Flags output stages will modulated thermal time constants; Figure Table below shows behavior Error Flags: Table Diagnosis Interpretation Error error overcurrent open load over voltage over temperature Error Flag behavior Output status latch auto recovery auto recovery normal operation latched switch normal operation auto recovery Priority

Over Voltage supply voltage rises above switch voltage VOVOFF, output transistors switched Error Flags set. error latched, i.e. falls again reaches switch voltage VOVON, power stages restarted Error Flags reset.
