Integrated clamp-diodes limit the output voltage peak when switching off an inductive load. For the detection of errors there are two status outputs, which monitor the following errors by logic levels: - thermal overload, - open and short load to ground in active an inactive mode, - overloading of output (also shorted load to supply) in active mode. Circuit Description Input Circuits The control and enable inputs, all active high, consist of Schmitt triggers with hysteresis. All inputs are connected with pull-down current sources. Not connected inputs are interpreted as "low". Switching Stages The power outputs consist of a DMOS power transistor with open drain. The output stages are shortload-protected throughout the operating range. Integrated clamp-diodes limit voltage spikes produced when inductive loads are discharged. Protective Circuit The outputs are protected against current overload. There is no protection against reverse polarity of the supply voltage. 5 6 VDSC is the output voltage of the other channel used for open load compare detection This parameter will not be tested but assured by design V5 Page 6 28.04.2002 Preliminary Datasheet TLE 6215 G 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 Also the output voltages of two outputs are compaired against each other in off S. 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 detection.
