Preliminary data sheet
7.1 Pinning
7.2 Pin description
The SO32 package has four corner leads. These leads (1, 16, 17 and 32) are internally
connected to the die pad and must be connected to V
copper area on the PCB these leads determine the ambient temperature, which affects
the thermal resistance of the junction.
