Protection and Diagnosis
4.4.1.1
Short Circuit of Output to Ground or Vs
The low-side switches are protected against short circuit to supply and the high-side
switches against short to GND.
If a switch is turned on and the current rises above the shutdown threshold
I
SD for longer
than the shutdown delay time
t
dSD, the output transistor is turned off and the
corresponding diagnosis bit is set. During the delay time, the current is limited to
I
SC as
shown in Figure 9.
Figure 9
Short circuit protection
The delay time ia relatively short (typ. 25 s) to limit the energy that is dissipated in the
device during a short circuit. This scheme allows high peak-currents as required in
motor-applications.
The output stage stays off and the error bit set until a status register reset is sent to the
SPI or a power-on reset is performed.
4.4.1.2
Cross-Current
If for instance HS1 is ON and LS1 is OFF, you can turn OFF HS1 and turn ON LS1 with
the same SPI command. To ensure that there is no overlap of the switching slopes that
would lead to a cross current, the dead-time H to L and L to H is specified.
In the control registers, it is also possible to turn ON high- and low-side switches of the
same half-bridge (e.g. LS1ON = H and HS1ON = H). To prevent a cross-current through
the bridge, such a command is not executed. Instead, both switches are turned OFF and
the Over-Load bit is set High for both switches (e.g. LS1OvL = H and HS1OvL = H).
