preliminary datasheet tle 6215 g v5 page 28.04.2002 7 error detection the status output signal of the switching stages at normal operation is low = off; high = on. in case of any error the status outputs are set according to the table below. if current overload or thermal overload occurs, the error condition is stored in an internal register and the output is shutdown. to reset this register the control input of the affected channel has to be switched off and then on again. the state of the error detection circuit is directly dependent on the input status. open load is detected for both on- and off-modus. in the on-modus the load current is monitored. if it drops below the specified threshold open load is detected. in the off mode, the ouput voltage is monitored. an open load condition is detected when the output voltage of a given channel is below 55 % of the supply voltage v s . also the output voltages of two outputs are compaired against each other in off condition with a fixed offset of typ. 1.25 v to recognize gnd bypasses. to suppress fault diagnosis during the flyback phase of the compared output, the diagnostic circuit includes a latch function. reset of this latch is done at end of the flyback phase, additionally it can be reseted by a low signal on the enable input and by a high signal of the input signal. see also the block diagramm of open load dete c - tion. diagnostic table operating condition inputs power outputs status outputs ena in1 in2 out1 out2 st1 st2 normal function l h h h h x l h l h x l l h h off off on off on off off off on on l l h l h l l l h h thermal overload x l h l x h l x h off off off off off off l l l l l l open load channel 1 x l h l h h 1) off off on 1) h h l 1) open load channel 2 x l h 1) l h h 1) off off on 1) h h l overload channel 1 l h h x l h 1) off off off 1) l l l 1) overload channel 2 l h h 1) x l h 1) off off off 1) l l l 1) see normal function
