SPI Diagnostics:
As soon as a fault occurs for longer than the fault filtering time, the fault information is latched into the
diagnosis register (and the Fault pin will change from high to low state). A new error on the same
channel will over-write the old error report. Serial data out pin (SO) is in a high impedance state when
CS
is high. If
CS
receives a LOW signal, all diagnosis bits can be shifted out serially. If the sent com-
mand was valid the rising edge of
CS
will reset the diagnosis registers (except the channel OT flag)
and restart the fault filtering time. In case of an invalid command the device will ignore the data bits and
the diagnosis register will not be reset at the rising
CS
edge.
Figure 1: Two bits per channel diagnostic feedback plus two overtemperature flags
For Full Diagnosis there are two diagnostic bits per channel configured as shown in Figure 1.
Diagnosis bit0 and bit1 are always set to 1.
Normal function:
The bit combination
HH
indicates that there is no fault condition, i.e. normal function.
Overload, Shorted Load or Overtemperature:
HL
is set when the current limitation gets active, i.e.
there is a overload, short to supply or overtemperature condition. The second reason for this bit combi-
nation is overtemperature of the corresponding channel.
Open load: LH
is set when open load is detected (in off state of the channel)
Switch Bypassed:
Short to GND :
in lowside configuration LL is set when this condition is detected
Short to Battery :
in highside configuration LL is set when this condition is detected
Channel Overtemperature Flag:
In case of overtemperature in any output channel in on state the
overtemperature Flag in the SPI diagnosis register is set (change bit 3 from 0 to 1). This Bit can be
used to distinguish between Overload and Overtemperature (both HL combination) and is reset by
switching OFF/ON the affected channel.
In addition the DIAG6 / Ovtertemp pin is set low (if configured as Overtemp.Flag).
IC Overtemperature Flag:
When the IC logic tremperature exceeds typ.170° the non-latching IC
Overtemperature Flag will be set in the SPI diagnosis register(change bit 2 from 0 to 1).
In addition the DIAG6 / Ovtertemp pin is set low (if configured as Overtemp.Flag).
