供应SILERGY/矽力杰SY6280AAC：
The SY6280 develops ultra-low Rds(on) switch with programmable current limiting to protect the power source from over current and short circuit conditions. It integrates the over temperature protection and discharges the output capacitor during the shutdown. In case the output is pulled higher than the input voltage under the shutdown, the SY6280 can block the current flowing from the output to the input.  
The SY6280 is a current limited P-channel MOSFET power switch designed for high-side load-switching applications. There is no parasitic body diode between drain and source of the MOSFET, so the SY6280 prevents current flow from out to input when out being externally forced to a higher voltage than vin when chip is disabled.
When the over-current condition is sensed, the gate of the pass switch is modulated to achieve constant output current. Under output short circuit conditions, the normal current limit folded back 50%. If the over current condition presists for a long enough time, the junction temperature may exceed 130C, and overtemperature protection will shut down the part. Once the chip temperature drops to 110C, the part will restart
In order to prevent the input voltage drooping during hot-plug events, a 10uF ceramic capacitor form VIN to GND is strongly recommended. However, higher capacitor values could reduce the voltage droop on the input further. Furthermore, an output short will cause ringing on the input without the input capacitor. It could destroy the internal circuitry when the input transient exceed 6V which is the absolute maximum supply voltage even for a short duration.
