2.21.5 Current Monitoring

INA228 power monitor devices are used to monitor current and voltage of various power rails of AM62P SoC. The INA228 interfaces to the AM62P SoC through I2C interface (SoC_I2C1). Four terminal, high-precision shunt resistors are provided to measure load current.

Note: The design supports current/voltage measurements using either INA228 or INA231. INA228 is only populated on the SK (Implemented through stacked PCB footprint).
