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.
Bit 6 and bit 7 of the diagnostic register are not used and always H.
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/ Under current: LH is set when open load (in off state of the channel) or under current (in
on state of the channel) is detected
Short to GND : LL is set when this condition is detected (in off state)
Channel Overtemperature Flag: In case of overtemperature in any output channel in on state the
overtemperature Flag in the SPI diagnosis register is set. This Bit can be used to distinguish between
Overload and Overtemperature (both HL combination).
IC Overtemperature Warning Flag: When the IC logic temperature exceeds typ.170° the IC
Overtemperature Warning Flag will be set in the SPI diagnosis register.
Parallel Status Output Diagnostics :
Parallel diagnostic outputs (open drain) change state according to the input signal of the corresponding
channel. As soon as an error occurs at the corresponding channel ( Overload, Overtemperature and
Under current is detected in on state and Open load, short to GND also in off state) the Status output
shows the inverted input signal. A fault is detected only if it lasts for longer than the fault filtering time.
This fault information is not latched.
