 General DescriptionK5G嘉泰姆

APL3540,APL3542A is a high-side power distribution controller forK5G嘉泰姆

an external N-channel MOSFET, allow for +12V and +19VK5G嘉泰姆

power-supply rails. The wrong input voltage protectionK5G嘉泰姆

function protects a wrong input adapter insertion. WhenK5G嘉泰姆

input voltage is out of the target input voltage range, the ICK5G嘉泰姆

is off.K5G嘉泰姆

The built-in under-voltage protection monitors the outputK5G嘉泰姆

voltage for short-circuit conditions. When output voltageK5G嘉泰姆

is less than 70% of VIN voltage, the IC will be shut down.K5G嘉泰姆

The over-current protection monitors the output currentK5G嘉泰姆

by using the voltage drop across the external MOSFET’sK5G嘉泰姆

RDS(ON). When output current reaches the trip point, the ICK5G嘉泰姆

will be shut down. The APL3540 also provides a short-K5G嘉泰姆
