Pinning information
7.1 Pinning
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
SSA
in the application. Together with
the applied copper area on the Printed Circuit Board (PCB) these leads determine the
ambient temperature, which affects the thermal resistance of the junction.
