The FA7618 is a low RDS(ON), 5A eFuse with a 26V high voltage rating. The programmable current limit protects the power source from over-current or short-circuits conditions. The device is controlled by an on/off input, which is capable of interfacing directly with low-voltage control signals. In FA7618, an option 2kΩ on-chip load resistor is added for output fast discharge when the switch is turned off.
Other features include a power-OK (POK) output that signals when the output voltage is ready.
