53 / 83 page  Datasheet 53 Rev. 1.0 2017-11-23 TLE75242-ESH SPIDER+ 12V Diagnosis 9.3.1 Open Load at ON - direct channel diagnosis When DIAG_OLONEN.MUX bits are programmed with a value corresponding to a channel (0010B → 0111B), the internal multiplexer checks for Open Load at ON condition on the selected channel. It is recommended that the channel is ON for at least tON before activating the diagnosis. After a time tOLONSET the corresponding DIAG_OLON.OUTn bit for the selected channel is available. All the other bits in the DIAG_OLON register are set to default (“0B”). The bits are updated every time the register is read. When a channel is selected, the corresponding DIAG_OLON.OUTn bit content is mirrored also in the Standard Diagnosis (bit OLON). In case of several register readouts in sequence the register content is updated at every read request from micro-controller. See Figure 30 for further details. Figure 30 Open Load at ON timings (direct channels diagnosis) 9.3.2 Open Load at ON - diagnosis loop When DIAG_OLONEN.MUX bits are programmed with the value 1010B, the device starts a diagnosis loop where all auto-configurable (when used as high-side switches) and high-side channels are checked for Open Load at ON. The internal multiplexer is controlled by the internal logic, therefore there is no need for the micro-controller to send any additional command. First the internal logic checks all channels which are directly driven by the micro-controller and not configured to be driven by the internal PWM generator, then the internal logic checks all channels which are configured to be driven by the internal PWM generator. • Diagnosis sequence for channels driven directly by the micro-controller – First channel checked: channel 2. It is recommended that the channels are ON at least tON before activating the diagnosis loop. –After a time tOLONSET + tSYNC the diagnosis for the first channel is completed (DIAG_OLON.OUTn bit is updated) – The internal multiplexer is set to the next channel. After a time tOLONSW + tSYNCthe diagnosis is completed (DIAG_OLON.OUTn bit is updated) for the currently selected channel. This step is repeated for all remaining directly driven channels.
