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. The over-current protection monitors the output current by using the voltage drop across the external sensing resistor, when output current reaches the trip point the IC will be shut down. The APL3542A also provides a shortcircuit protection during power-up. The device monitors VOUT voltages for a short-circuit detection, if a short-circuit condition is detected the IC will be shut down. Other features include a POK output to indicate the output voltage is ready, and a logic-controlled shutdown mode.
Features
- High-Side Driver for an External N-Channel MOSFET
