3 Device and Test Board Information

The TPS7H502x-SEP is packaged in a 24-pin HTSSOP PWP plastic package as shown in Figure 3-1. A custom TPS7H502x-SEP evaluation module, designed for open-loop SEE testing was used to evaluate the performance and characteristics of the TPS7H502x-SEP under heavy ion radiation. The evaluation module is shown in Figure 3-2. The schematics are shown in Figure 3-2 and Figure 3-4.
