APL3514 Power-Distribution Switches with Soft Start Features • • • • • • • • • • 90mΩ High Side MOSFET 2A Continuous Current Bulit-In 2ms Soft Start Control Wide Supply Voltage Range: 2.7V to 5.5V Current-Limit and Short-Circuit Protections Under-Voltage Lockout Protection Reverse Current Blocking when Switch Disabled Over-Temperature Protection Logic Level Enable Input APL3514A: Active High APL3514B: Active Low Lead Free and Green Devices Available (RoHS Compliant) General Description The APL3514A/B is a power-distribution switch with some protection functions that can deliver current up to 2A. The device incorporates a 90mΩ N-channel MOSFET power switch that is controlled by an enable logic pin and has internal soft start control to minimize inrush current. The device integrates some protection features, including current-limit protection, short-circuit protection, overtemperature protection, and UVLO. The 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. 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-23-5 packages with enable active-high(EN) and active-low(ENB) versions.

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).
