NCP349 Positive Overvoltage Protection Controller with Internal Low RON NMOS FET The NCP349 is able to disconnect the systems from its output pin when wrong input operating conditions are detected. The system is positive overvoltage protected up to +28 V. This device uses an internal NMOS and therefore, no external device is necessary, reducing the system cost and the PCB area of the application board. The NCP349 is able to instantaneously disconnect the output from the input, due to integrated.

www.DataSheet4U.com NCP3488 MOSFET Driver with Dual Outputs for Synchronous Buck Converters The NCP3488 is a single Phase 12 V MOSFET gate driver optimized to drive the gates of both high−side and low−side power MOSFETs in a synchronous buck converter. The high−side and low−side driver is capable of driving a 3000 pF load with a 25 ns propagation delay and a 20 ns transition time. With a wide operating voltage range, high or low side MOSFET gate drive voltage can be optimized for the best effic.

28V Overvoltage Protection

NCP349 Positive Overvoltage Protection Controller with Internal Low RON NMOS FET The NCP349 is able to disconnect the systems from its output pin when wrong input operating conditions are detected. The system is positive overvoltage protected up to +28 V. This device uses an internal NMOS and therefore, no external device is necessary, reducing the system cost and the PCB area of the application board. The NCP349 is able to instantaneously disconnect the output from the input, due to integrated Low RON Power NMOS (65 mW), if the input voltage exceeds the overvoltage threshold (OVLO) or falls below the undervoltage threshold (UVLO). At powerup (EN pin = low level), the Vout turns on ton time after the Vin exceeds the undervoltage threshold. The NCP349 provides a negative going flag (FLAG) output, which alerts the system that a fault has occurred. In addition, the device has ESD−protected input (15 kV Air) when bypassed with a 1.0 mF or larger capacitor.
