13 / 54 page  AN3981 8-bit LED array drivers Doc ID 022217 Rev 1 13/54 Figure 10. Fault conditions detected by error detection mode: a) shorted LED; b) open LED; c) short-circuit from current generator to VLED; d) open channel; e) short-circuit from current generator to GND The diagnostic circuitry embedded in the STP08DP05 can detect these faulty conditions (in accordance with the detection thresholds of Table 1) and provide the results of the detection as an “Error status code” coming out of the SDO pin (see Figure 11), with “0” logic level indicating a faulty channel, whereas a “1” logic level indicates a “good” channel. Table 1. Detection conditions Detection conditions Detection result IODEC (1) = 0.5·I O (2) 1. IODEC is the detected output current in detection mode. 2. IO is the programmed output current. Open channel or output short to GND detected IODEC = 0.5·IO No error detected VO = 2.5 V LED short-circuit or LED shorted to supply voltage VO = 2.2 V No error detected |
