 /*
  * Psys_pmax considerations.
  *
  * Given the hardware design in kuldax, the serial shunt resistor is 0.005ohm.
- * The full scale of hardware PSYS signal 1.6v maps to system current 7.5A
+ * The full scale of hardware PSYS signal 1.6v maps to system current 11.25A
  * instead of real system power. The equation is shown below:
- * PSYS = 1.6v = (0.01ohm x 7.5A) x 50 (INA213, gain 50V/V) x R501/(R501 + R510)
- * R501/(R501 + R510) = 0.858 = 20K / (20K + 3.3K)
+ * PSYS = 1.6v = (0.005ohm x 11.25A) x 50 (INA213, gain 50V/V) x R501/(R501 + R510)
+ * R501/(R501 + R510) = 0.57 = 20K / (20K + 15K)
  *
  * The Psys_pmax is a SW setting which tells IMVP9.1 the mapping b/w system input
  * current and the actual system power. Since there is no voltage information
  * from PSYS, different voltage input would map to different Psys_pmax settings:
- * For Type-C 15V, the Psys_pmax should be 15v x 7.5A = 112.5W
- * For Type-C 20V, the Psys_pmax should be 20v x 7.5A = 150W
- * For a barrel jack, the Psys_pmax should be 20v x 7.5A = 150W
+ * For Type-C 15V, the Psys_pmax should be 15v x 11.25A = 168.75W
+ * For Type-C 20V, the Psys_pmax should be 20v x 11.25A = 225W
+ * For a barrel jack, the Psys_pmax should be 20v x 11.25A = 225W
  *
  * Imagine that there is a type-c 100W (20V/5A) connected to DUT w/ full loading,
- * and the Psys_pmax setting is 150W. Then IMVP9.1 can calculate the current system
- * power = 150W * 5A / 7.5A = 100W, which is the actual system power.
+ * and the Psys_pmax setting is 225W. Then IMVP9.1 can calculate the current system
+ * power = 225W * 5A / 11.25A = 100W, which is the actual system power.
