APL3517
The APL3517/A/B is a power-distribution switch with current- limiting function and output OVP protections that can deliver current up to 0.1A. The device incorporates a 250mΩ N-channel MOSFET power switch. The device integrates some protection features, including current-limit protection, output over-voltage protection, over-temperature protection and UVLO. The current-limit protection can protect down-stream devices from catastrophic failure by limiting the output current at currentlimit threshold during over-load or short-circuit events. The output over-voltage protection can prevent current flowing from VOUT to VIN when an abnormally high voltage exists in VOUT. The 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. The device is available in lead free SOT-23-3 and SOT-23-5 packages.

Note: ANPEC lead-free products contain molding compounds/die attach materials and 100% matte tin plate termination finish; which are fully compliant with RoHS. ANPEC lead-free products meet or exceed the lead-free requirements of IPC/JEDEC J-STD-020D for MSL classification at lead-free peak reflow temperature. ANPEC defines “Green” to mean lead-free (RoHS compliant) and halogen free (Br or Cl does not exceed 900ppm by weight in homogeneous material and total of Br and Cl does not exceed 1500ppm by weight).
