TDA7476
12/19
READ BYTE 1
READ BYTE 2
READ BYTE 3
When the
P reads correctly all the 3 bytes containing the mentioned information and gives the last acknowl-
edge, the TDA7476 switches to the "permanent diagnostic operation"
B) PERMANENT DIAGNOSTIC
It can sense the following diagnostic information:
CH1, CH2, CH3, CH4, CH5
- Short Circuit to GND
- Short Circuit to Vs
Aux1, Aux2
- Short Circuit to GND (*)
- Open Load (*)
(*) Detected if the high side drivers attached to the Aux outputs are ON.
In this case the above conditions are not detected while the single infrasonic current pulse is present but be-
fore. The fault condition must be present for more than 2sec. (typ) and must be also true during the pulse,
where the data are memorized and then transmitted.The bytes from/to
P and TDA7476 are the same as
those in case of turn-on diagnostic (see above).
Here following is the permanent diagnostic output Data Bytes. The bits D7 and D6 of the first byte both stand at
0 level. This condition, although not possible during the turn-on diagnostic, can be useful to confirm that the
bytes are referred to the permanent diagnostic.
