... ON, it pull the DIA pin low. This pin is known as K line in the ISO 9141 specification. The DIA pin structure is open collector, without pull up component. This allow the connection of several MC33199 on the K line and the use of a single pull up resistor per system (see to protect the DIA pin against short circuits to VBAT, the device incorporates a current limitation (see thermal shutdown ...
