 General DescriptionVWw嘉泰姆

APL3540,APL3542A is a high-side power distribution controller forVWw嘉泰姆

an external N-channel MOSFET, allow for +12V and +19VVWw嘉泰姆

power-supply rails. The wrong input voltage protectionVWw嘉泰姆

function protects a wrong input adapter insertion. WhenVWw嘉泰姆

input voltage is out of the target input voltage range, the ICVWw嘉泰姆

is off.VWw嘉泰姆

The built-in under-voltage protection monitors the outputVWw嘉泰姆

voltage for short-circuit conditions. When output voltageVWw嘉泰姆

is less than 70% of VIN voltage, the IC will be shut down.VWw嘉泰姆

The over-current protection monitors the output currentVWw嘉泰姆

by using the voltage drop across the external MOSFET’sVWw嘉泰姆

RDS(ON). When output current reaches the trip point, the ICVWw嘉泰姆

will be shut down. The APL3540 also provides a short-VWw嘉泰姆
