72 / 170 page  Functional description L9779WD 72/170 DocID027452 Rev 5 Short circuit to battery When the load is on, if the voltage of IGNx is bigger than the Vign_scb threshold for a time longer than Tign_filt the SCB fault is detected and the output IGNx becomes high impedance. When the load is off, if the voltage of IGNx is bigger than the Vign_scb threshold for a time longer than Tign_filt the SCB fault is detected and the output IGNx becomes high impedance. The SCB fault has a higher priority with respect to the OL fault. According to the IGN_DIA_MODE bit, two behaviors are possible: 1. Latch mode The fault is latched and is reset at every Read Diag operation. The high impedance is removed and IGNx is driven by the command: – after a Read Diag operation – if the command is switched OFF and ON again. 2. No latch mode The fault is not latched and if the voltage of IGNx is lower than the Vign_scb threshold for a time longer than Tign_filt the fault state disappears and the high impedance is removed. |
