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 short- load-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 V DSC is the output voltage of the other channel used for open load compare detection 6 This parameter will not be tested but assured by design |
