General Description
The APL3535 is a power-distribution switch with some protection functions that can deliver current up to 7A. The device incorporates a 12mΩ N-channel MOSFET power switch that is controlled by an enable logic pin and has a SS pin dedicated to soft start ramp-up rate control that can be used in application where the inrush current is concerned. The APL3535 integrates some protection features, including current limit protection, over temperature protection. The current limit protection can protect down-stream devices from catastrophic failure by limiting the output current at current-limit threshold during over-load or short-circuit events. The over temperature protection function shuts down the N-channel MOSFET power switch when the junction temperature rises beyond 155°C. Other features include an accurate current monitor function. The device is available in lead free QFN2x2-12A package.
