      CXES4270 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 CXES4270 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.
