Notes

11.

The supply current depends on operation mode and can be calculated as follows:

•Start-Up Mode: IIN = 539 µA + 548 µ * ICHG(A) + 216 µ * ILIM(A) + VPWR(V) / 460(kΩ)

•Normal Mode: IIN = 539 µA + 240 µ * ILIM(A) + 288 µ * ILOAD(A) + VPWR(V) / 460(kΩ)

•Overcurrent Mode: IIN = 539 µA + 612 µ * ILIM(A) + VPWR(V) / 460(kΩ)

•Disable Mode: IIN = 539 µA + 240 µ * ILIM(A) + IDIS(µA) + VPWR(V) / 460(kΩ)
