Notes
11. The supply current depends on operation mode and can be calculated as follows:
•Start-Up Mode: I_IN = 539 µA + 548 µ * I_CHG(A) + 216 µ * I_LIM(A) + V_PWR(V) / 460(kΩ)
•Normal Mode: I_IN = 539 µA + 240 µ * I_LIM(A) + 288 µ * I_LOAD(A) + V_PWR(V) / 460(kΩ)
•Overcurrent Mode: I_IN = 539 µA + 612 µ * I_LIM(A) + V_PWR(V) / 460(kΩ)
•Disable Mode: I_IN = 539 µA + 240 µ * I_LIM(A) + I_DIS(µA) + V_PWR(V) / 460(kΩ)
