52 / 82 page  Datasheet 52 Rev. 1.0 2017-11-23 TLE75602-ESH SPIDER+ 12V Diagnosis Figure 28 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) 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. – If one channel is OFF when the diagnosis is performed, the corresponding DIAG_OLON.OUTn is set to “0B” • Diagnosis sequence for channels driven by the internal PWM Generators (see Chapter 7.5) – These channels are diagnosed only after all channels directly driven by micro-controller are checked – Channels mapped to PWM Generator 0 are diagnosed first –After a time tOLONSET the channel activation (switch ON) is the trigger event to perform Open Load at ON diagnosis for the first channel –After a time tONMAX + tOLONSW the diagnosis for the first channel is completed (DIAG_OLON.OUTn bit is updated) INn ILn t OpenLoadON_direct.emf OUT.OUTn DIAG_OLONEN.MUX 1111 ≠ 1111 (ch. n) tON t t tOLONSET DIAG_OLON.OUTn 0 t t SPI readout of DIAG_OLON.OUTn 1 0 1 IL(OL) tOLONSW tOLONSW |
