APL3540 is a high-side power distribution controller for

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

power-supply rails. The wrong input voltage protection

function protects a wrong input adapter insertion. When

input voltage is out of the target input voltage range, the IC

is off.

Features

General Description

Applications

•

Desktop PCs

The built-in under-voltage protection monitors the output

voltage for short-circuit conditions. When output voltage

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

The over-current protection monitors the output current

by using the voltage drop across the external MOSFET’s

R

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

circuit protection during power-up. The device monitors

DRV and VOUT voltages for a short-circuit detection. If a

short-circuit condition is detected, the IC will be shut

down. Other features, including a POK output which indi-

cates that the output voltage is ready and a logic-con-

trolled shutdown mode.
