Features General Description - 60mΩ High Side MOSFET The APL3522A/B is a power-distribution switch with some - 2.5A Continuous Current protection functions that can deliver current up to 2.5A. - Programmable VOUT Discharge Function by DIS The device incorporates a 60mΩ N-channel MOSFET Pin power switch that is controlled by an enable logic pin and - Wide Supply Voltage Range: 2.7V to 5.5V - Current-Limit and Short-Circuit Protections dedicated to soft-start ramp-up rate control that can be used in application where the inrush current is concerned. It can be programmable VOUT discharge function by DIS - Under-Voltage Lockout Protection pin. - Reverse Current Blocking when Switch Disabled The device integrates some protection features , includ- - Over-Temperature Protection ing current-limit protection, short-circuit protection, over- - Logic Level Enable Input APL3522A: Active High APL3522B: Active Low - UL Approved-File No. E328191 - UL-CB Scheme IEC/EN62368-1 Certified - TUV IEC/EN62368-1 Certified - Lead Free and Green Devices Available temperature 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 (Ro HS pliant) rises beyond 140o C and will automatically turns on the power switch when the temperature drops by 20o C. 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.
