PRODUCTION DATA.
A 100-kΩ resistor is connected from this pin to GND. This pin sets the reference current required to bias the internal circuitry of the device. The overload current limit tolerance and CC currents depend upon the accuracy of this resistor. A ±0.5% low temp CO resistor, or better, yields the best current limit accuracy and overall device performance. If the CC capability broadcast will only be set to STD (CHG pulled low) then up to a ±10% resistor may be used as long as the additional error in the current limit is acceptable.
