Analog Integrated Circuit Device Data Freescale Semiconductor 5 34653 ELECTRICAL CHARACTERISTICS STATIC ELECTRICAL CHARACTERISTICS STATIC ELECTRICAL CHARACTERISTICS Table 3. Static Electrical Characteristics Characteristics noted under conditions 36 V ≤ VPWR ≤ 80 V and -40°C ≤ TA ≤ 85°C. All voltages are referenced to VIN unless otherwise noted.

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) 12.
