6.6 Switching Characteristics

Unless otherwise noted –40°C ≤ T_J ≤ 125°C and 4.5 V ≤ V_(IN) ≤ 6.5 V, V_(EN) = V_(IN), V_(CTL1) = V_(CTL2) = V_(IN). R_(FAULT) = R_(STATUS) = 10 kΩ, R_(IMON) = 2.55 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.
