This test analyzes the response of the TIDA-020065 to a 1000μF capacitive load.
Figure 4-8 shows the system immediately enters precharge mode upon power up. In hardware, the slew rate control is set to slowly drive the low power path so the load capacitor can be charged in 10ms, which explains why the peak current pulse lasts for about 10ms. After 15ms, the MSPM0L1306-Q1 transitions the system over to active mode by driving the main FET gate (G1). The current probe used in this test is locked to 5A/V, so the actual measured peak current was about 1.3A.
