BQ4050: Current detection

shimao zhu

Part Number: BQ4050

The current ADC provided in the specification is 16-bit, but it is recommended to use a current-carrying resistor of 1 to 3mΩ. Will this cause smaller currents to fail to be detected

Please reference this application note below, but typically the higher resistor leads to a higher resolution.
