The short circuit to ground detection is activated when the current through one of the high side switches rises over
the threshold I
The output stage in which the short circuit was detected will be switched off within t
In H-bridge mode also the other output will be switched off after a short delay of t
In single switch mode only the affected output will be switched off.
8.5
A short circuit to battery is detected in the same way as a short circuit to ground, only in the low side switch instead
of the high side switch.
8.6
Short circuit over load is indicated by two failures - short circuit to ground on one output and short circuit to battery
on the other output. Both failure bits will be set in the SPI diagnostics register. Both output stages will be turned off.
8.7
In case of high DC-currents, insufficient cooling or high ambient temperature, the chip temperature may rise above
the thermal shut-down temperature
8.8
If the supply voltage at the VS pins falls below the undervoltage detection threshold V
are turned off. As soon as
8.9
Open load diagnosis is only possible if outputs are switched off by DIS or ABE. The diagnostic current sources are
deactivated in status flag mode. Diagnostic current sources are disconnected if outputs are active. That means
that the diagnostic current sources are also disconnected if the outputs are deactivated due to short circuit. The
open load detection in H-bridge mode is different from the open load detection in single switch mode.
