The TLE8102SG provides diagnosis information about the device and about the load. The following diagnosis
functions are implemented:
•
•
•
•
The diagnosis information of the TLE8102SG can either be accessed by status (ST) pins or the SPI interface
and/or fault pin. With the exception of over temperature, a fault is only recognized if it lasts longer than the fault
delay time t
the input signal of the corresponding channel. If a fault condition appears and the fault delay time elapses, the
status pin for the channel shows the inverted input signal. This diagnosis flag is not latched. Therefore, if the fault
condition is removed, the status pins will indicate normal operation.
Unlike the status pins, when using the SPI interface and/or fault pin, diagnosis flags are latched in the diagnosis
register of the SPI interface. In this case, diagnosis flags are cleared by the rising edge of the
successful SPI transmission.
