Anpec Electronics Corporation announced that the APL3534/A/B is a power-distribution switch with current-limiting function and output OVP protections that can deliver current up to 1A. The device incorporates a 110mW 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 high voltage exist in VOUT. The over temperature protection function shut 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 low 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.
