4.5.14.5 Current Monitoring

INA231 power monitor devices are used to monitor current and voltage of various power rails of AM62A Low Power processor.The INA231 interfaces to the AM62A Low Power through I2C interface (SoC_I2C1). Four terminal, high precision shunt resistors are provided to measure load current.
