Electrical Characteristics (continued)
Unless otherwise noted, –40°C
≤ TJ ≤ 125°C and 4.5 V ≤ V(IN) ≤ 6.5 V, V(EN) = V(IN), V(CTL1) = V(CTL2) = V(CTL3) = V(IN). R(FAULT) =
R(STATUS) = 10 kΩ, R(ILIM_HI) = 19.1 kΩ, R(ILIM_LO) = 80.6 kΩ. Positive currents are into pins. Typical values are at 25°C. All
voltages are with respect to GND.
