  • Low ON resistance : 50mΩ (typ) at a supplyvoltage of 5V
  • Flexible overvoltage-protection trip level
- Wide adjustable OVLO threshold range from 4V to 20V
- Preset internal accurate OVLO threshold : 6.8V
  • Low quiescent current 70µA
  • Internal 8ms startup debounce
  • Protection circuitry :
- Surge Immunity to 100V
- Overvoltage lockout
  • Low Capacitance ESD Protection
  • Available in TDFN3x3-10 Packages
  • Lead Free Green Devices Available (RoHS Compliant)

General Description
The APL3228 overvoltage protection devices feature a low 50mΩ (typ) RON internal FET and protect low-voltage systems against voltage faults up to +28VDC. An internal clamp also protects the devices from surges up to +100V. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected downstream components. The overvoltage protection threshold can be adjusted with optional external resistors to any voltage between 4V and 20V. With the OVLO input set below the external OVLO select voltage, the APL3228 automatically choose the accurate internal trip thresholds. The internal overvoltage thresholds (OVLO) are preset to 6.8V. The devices feature an open-drain (ACOK)' output indicating a stable supply between minimum supply voltage and VOVLO. The APL3228 are also protected against over current events by an internal thermal shutdown.

  • 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 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.

General Description
APL3548 is a high-side power distribution switch, allow for +12V, +19V or +9.5V power-supply rail. The wrong input voltage protection function protects a wrong input of adapter insertion, when input voltage is out of the target input voltage range the IC is off. The APL3548 provides a short-circuit protection during power-up. When a short circuit is present before soft start, the IC will limit the output current at 300mA during dead short condition (VOUT<1V) unless the short circuit has been removed and the output voltage has risen above 1V. After power-up the OCP function prevents the IC from catastrophic failure from over-load and short circuit conditions. If an OC event is detected, the IC immediately shuts down the internal power switch and will initiate a new soft start cycle. The OCP tripping threshold is set by the external resistor on OCSET pin. Other features include an adjustable soft start time and a logic-controlled shutdown mode. The device is available in SOP-8P and TDFN3x3-10 Packages.

General Description
The APL3557 is a power-distribution switch with some protection functions that can deliver current up to 5A. The device incorporates a 12mΩ 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, over temperature protection, and input over voltage protection. The current limit 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. The over temperature protection function shuts down the N-channel MOSFET power switch when the junction temperature rises beyond 140°C. Other features include an accurate current monitor function. The device is available in lead free VTQFN2x3-17 package.

General Description
The APL6003 overvoltage protection devices feature a low 15mΩ (max) RON internal FET and protect low-voltage systems against voltage faults up to +25VDC. An internal clamp also protects the devices from surges up to +120V. When the input voltage exceeds the overvoltage threshold, the internal FET is turned off to prevent damage to the protected downstream components. The overvoltage protection threshold can be adjusted with optional external resistors to any voltage between 4V and 24V. With the OVLO input set below the external OVLO select voltage, the APL6003 automatically choose the accurate internal trip thresholds. The internal overvoltage thresholds (OVLO) are preset to 5.95V typical. The devices feature an open-drain (ACOK)' output indicating a stable supply between minimum supply voltage and VOVLO. The APL6003 are also protected against over current events by an internal thermal shutdown.
