¡El APL3512A/B is a power-distribution switch with some protection functions that can deliver current up to 2A. The device incorporates a 90mW 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. ¡El device integrates some protection features, including current-limit protection, short-circuit protection, overtemperature protection, and UVLO. ¡El current-limit and short-circuit 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. When VOUT drops below VIN-1.5V the devices limit the current to a lower and safe level. ¡El over-temperature protection function shuts down the N-channel MOSFET power switch when the junction temperature rises beyond 140oC and will automatically turns on the power switch when the temperature drops by 20oC. The UVLO function keeps the power switch in off state until there is a valid input voltage present. ¡El device is available in lead free SOT-23-5, TDFN2x2- 6 and SOP-8 packages with enable active-high(EN) and active-low(ENB) versions.
