Overview
APL3540 High-Side Power Distribution Controller Features • • • • • • • • • High-Side Driver for an External N-Channel MOSFET Under-Voltage Lockout (UVLO) Wrong VIN Input Voltage Protection Output Under-Voltage Protection (UVP) Short-Circuit Protection During Power-Up (SCP) Over-Current Protection (OCP) Shutdown Function Power-Ok (POK) Function Lead Free and Green Devices Available (RoHS Compliant) General Description 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.
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 RDS(ON).
When output current reaches the trip point, the IC will be shut down.
The APL3540 also provides a shortcircuit 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 indicates that the output voltage is ready and a logic-controlled shutdown mode.
