SBOK097B April 2025 – June 2025 TMP9R01-SEP
SEL testing was captured with the TMP9R01EVM. An SMU was used to supply max voltage (3.6V) and measure current through TP2 and GND. The R21 resistor was removed, the Subregulator Switch was switched off, and TP1 and TP2 was supplied at maximum voltage 3.6V.

Figure 5-5 Full Lab SEL Set UpSET testing for TMP9R01 has a separate board. The board was designed to capture transient data from the DUT and report the values in an excel sheet. More information about what was captured is presented in the Summary of SET Results Section. The board schematic, layout, and setup is shown below. TMP9R01 SET test setup was combined with other devices to multitask and only the TMP9R01 data is presented in this report.
