If short circuit messages from high- and low-side switch occur simultaneously within a
delay time of typically 2 s, the error bit “Short Circuit Over Load”, SCOL is set.
2.3.4
In case of high DC-currents, insufficient cooling or high ambient temperature, the chip
temperature may rise above the thermal shut-down temperature
output transistors are shut-down and the error-bit “Over-Temperature”, OT is set.
2.3.5
If the supply-voltage at the
outputs are set to tristate and the error-bit “Under-Voltage at
2.4
The Diagnosis-Mode can be selected between SPI-Diagnosis and Status-Flag
Diagnosis. The choice of the Diagnosis-Mode is selected by the voltage-level on Pin 12
(DMS Diagnosis Mode Selection):
• DMS = GND, Status-Flag Mode
• DMS =
For the connection of Pins SDI, SDO, CSN and SCK/SF see Figure 14 and Figure 15.
