70mΩ High Side MOSFET Continuous Current -APL3520A/B: 1.5A -APL3520C/D: 1A
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 140 oC in case of short circuit or over load conditions.
