Hello @�?��? 岩原 and welcome to the ST Community.

The slug (heat pad) is internally connected to the pins 1,10,11 and 20 (GND pins).

You can solder the slug on the PCB to improve power dissipation maximizing the ground layer.

Let me know if I addressed your concerns, if so please "Select as Best" label
