The TLE 7209-2R is protected against short circuits, overload and invalid supply voltage
by the following measures:
2.3.1
The high-side switches are protected against a short of the output to ground by an over
current shut-down. If a high-side switch is turned on and the current rises above the short
circuit detection current
of 2 µs, and the error bit “Short Circuit to Ground on output 1 (2)”, SCG1 (SCG2) is stored
in the internal status register.
2.3.2
Due to the chopper current regulation, the low-side switches are already protected
against a short to the supply voltage. To be able to distinguish a short circuit from normal
current limit operation, the current limitation is deactivated for the blanking time
the current has exceeded the current limit threshold
current
Figure 5). All output transistors are turned OFF and the according error bit “Short Circuit
to Battery on output 1 (2)”, SCB1 (SCB2) is set.
