Electrical Characteristics

Conditions are -40 ≤ TJ ≤ 125°C unless otherwise noted. VEN = VIN = 5 V, RFAULT# = RSTATUS# = 10 kΩ, RILIM_L = 80 kΩ, RILIM_H

= 20 k

Ω, ILIM_SEL = VIN, CTL1 = CTL2 = CTL3 = VIN, unless otherwise noted. Positive currents are into pins. Typical values are

at 25°C. All voltages are with respect to GND unless otherwise noted.
