Dual USB Switch with Fault

Blanking and Autoreset

ELECTRICAL CHARACTERISTICS (continued)

(Circuit of Figure 1, VIN = VIN_ = VON_ = 5V (MAX1823B/MAX1823H); VIN = VIN_ = 5V, ON_ = GND (MAX1823/MAX1823A), TA = -40°C

to +85°C, unless otherwise noted.) (Note 2)

Note 1: The output voltage at which the device transitions from short-circuit current limit to continuous current limit.

Note 2: Specifications to -40°C are guaranteed by design, not production tested.

Note 3: Reverse current (current from OUT_ to IN_) is blocked when disabled.

Note 4: Forward current (current from IN_ to OUT_) is internally limited. Reverse current, from OUT_ to IN_, is not limited when the

device is enabled and must be kept below 1.5ARMS to prevent permanent device damage. When the MAX1823A/MAX1823B

are disabled, the switch turns off and reverse current is internally blocked.

Typical Operating Characteristics

(Circuit of Figure 1, VIN = VINA = VINB = 5V, ON_ = GND (MAX1823/MAX1823A), ON_ = IN_ (MAX1823B/MAX1823H), TA = +25°C,

unless otherwise noted.)
