NCP374MU075GEVB: Overvoltage Up to +30 V and Down to -30 V with Load Switch Function Evaluation Board
The NCP374MU075GEVB evaluation board is designed to quickly assess the NCP374, an overvoltage, overcurrent and reverse control device. Two main modes are available by setting logic pins.First mode is Charging Mode from Wall Adapter to the system or from Vbus port to downstream DCDC. In this mode the system is both positive and negative overvoltage protected up to +28 V and down to -28 V. The wall adapter is disconnected from the system if the input voltage exceeds the overvoltage (OVLO) or undervoltage (UVLO) thresholds.The second mode, called the Reverse Mode, allows an external accessory to be powered by the system battery or supply upstream accessory through Vbus port. Here, the external accessory would be connected to the device input (bottom connector of system) and the device battery would be at the device output. In this case, overcurrent protection (externally adjustable) is activated to prevent accessory faults and battery discharge. Thanks to the NCP374 using an internal NMOS, the system cost and the PCB area of the application board are minimized. The NCP374 provides also negative going flag (FLAG(BAR)) 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 μF or larger capacitor. For more information please see the datasheet.
