PRODUCTION DATA.
The charge current is set with an external resistor connected form ISET to GND.
The resulting charge current is calculated by Equation 8:
Additionally, the charge current can be scaled to 100%, 75%, 50%, or 25% of the value set by Rset by software in register CHCONFIG1 using Bits ICH_SCL[1,0]. Precharge current and termination current is scaled accordingly.
