APL3512A : Active High
APL3512B : Active Low
  • Lead Free and Green Devices Available (RoHS Compliant)

General Description
The APL3512A/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 a SS pin dedicated to soft-start ramp-up rate control that can be used in application where the inrush current is concerned. 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, TDFN2x2-6 and SOP-8 packages with enable active-high (EN) and active-low (ENB) versions.

General Description
The APL3520 series of power switches are designed for USB applications. The 70mΩ N-channel MOSFET power switch satisfies the voltage drop requirements of USB specification. The protection features include current-limit protection, short circuit protection, and over-temperature protection. The device limits the output current at current limit threshold level, and when VOUT drops below 1.5V, the devices limit the current to a lower and safe level. The OTP limits the junction temperature below 140oC in case of short circuit or over load conditions. Other features include deglitched OCBx output to indicate the fault condition and ENx input to turn on or turn off output.

  • Lead Free and Green Devices Available (RoHS Compliant)

General Description
The APL3521A/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. 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.
