Tool/software: Linux
My settings:
GPADC_SMPS_ILMONITOR_EN register value = 0x24 (SMPS_ILMON_EN=1 | SMPS_ILMON_SEL=4 [smps7])
SMPS7 voltage = 1.8 volts
Load on SMPS7 rail = 1000 ohm radial resistor
When SMPS7 is active, the GPADC SW_CONV0 registers report ~ 0x212 (530 decimal)
When SMPS7 is inactive, the GPADC SW_CONV0 register report ~0xe (14 decimal)
Are these values GPDAC codes?
If I plug these values into Equation 1 in the TSP659037 data sheet section 5.3.2.1.3, I end up with:
IL (smps7 active) = IFS0 * (0.129) – IOS0 = 3.958 A * 0.129 – 0.652 A = –0.141 A
IL (smps7 inactive) = IFS0 * (0.00342) – IOS0 = 3.958 A * 0.00342 – 0.652 A = –0.638 A
What am I doing wrong? I am expecting values close to 0.0018 A and 0 A, respectively, since the voltage is 1.8 volts and the load is 1000 ohms.
