Port current is monitored continuously when:
The I2C data transmission is a 2-byte transfer.
NOTE
The conversion is done using a TI-proprietary multi-slope integrating converter.
Bit Descriptions
Port n Current[13:0]: 14-bit data conversion result of current for Port n. The result depends on whether the current-sense resistor is 250 mΩ or 255 mΩ.
The equation defining the current measured is:
where
RS = 255 mΩ | RSENSE = 250 mΩ | ||
