FEATURES
- Compliant to USB specifications - Dual independent switches control - 2.7V to 5.5V input voltage - 500mA minimum continuous current per port - 110mΩ typical on-resistance - 0.75A maximum short circuit current limit - Independent open-drain fault flag pins - 110μA typical on-state supply current - 1μA typical off-state supply current - Output can be forced higher than input (off-state) - Thermal shutdown - 2.4V typical under voltage lockout (UVLO) - 1ms turn-on (soft-start) and fast turn-off - Enable active-high (H) or active-low (L) - 8-pin SOP and PDIP packages GENERAL DESCRIPTION
Soft start eliminates the momentary voltage drop on the upstream port that may occur when the switch is enabled in bus-powered applications. Additional features include thermal shutdown to prevent catastrophic switch failure from high-current loads, under voltage lockout (UVLO) to ensure that the device remains off unless there is a valid input voltage present, and 3.3V and 5V logic compatible enable inputs.
