T1 and T2 are MOSFETS.
As per the datasheet:
Externally adjustable current limit If the device is conducting, the sense current can be used to reduce the short circuit current and allow higher lead inductance (see diagram above). The device will be turned off, if the threshold voltage of T2 is reached by ISRIS . After a delay time defined by RVCV T1 will be reset. The device is turned on again, the short circuit current is defined by IL(SC) and the device is shut down after td(SC) with latch function.
I am surprised Infineon used a poor symbol for a MOSFET right there...

3\$\begingroup\$ The symbol used is conventionally used to draw the schematic within an integrated circuit. It is sometimes difficult to decide if a particular device is N or P channel when the functions include N, P and transmission configurations.
