The FA7642 is a low RDS(ON), eFuse with 30V high voltage rating, and is able to drive 3A continuous Current. The adjustable current limit to protect the power source from over current or short circuit conditions. The power switch is controlled by an on/off input, which is capable of interfacing directly with low-voltage control signals. In FA7642, an on-chip load resistor is added for output fast discharge when switch is disabled. The FA7642 also supports Fast Role Swap as defined in the USB Power Delivery specification.
The power path supports OCP, SCP, OVP, RCP, and OTP features. The FLAGb signal remains asserted to indicate fault events until the fault condition is removed and the device resumes normal operation. The FA7642 is designed to eliminate false fault reporting by using an internal deglitch circuit.
