NCP349GEVB NCP349 Evaluation Board User's Manual Description 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). 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. http://onsemi.com EVAL BOARD USER’S MANUAL Figure 1.

CMS0603 0.5% Jumper Ground 1 mm pitch 10.16 mm CONNECTING PROCESS Turn On. 1. Connect a supply (5 V typical, Maximum rating, 7 V) on Vcc test point. 2. Let EN_STATE strap on right side if you want to Enable the device. (Pull down to GND). 3. Connect Vin on INPUT test point. Typical UVLO current consumption is 70 mA. Typical current consumption UVLO < Vin < OVLO without load is 170 mA. 4. Connect the system on OUTPUT test point. 5. Increase Vin level above UVLO to see Vin on Vout pin. 6. Connect strap on left side to disable the part (disconnect Vout from Vin) Turn Off. 1. Disconnect system connected on Vout connector. 2. Disconnect Vin or adapter connected on Vin connector. 3. Disconnect Vcc supply. ON Semiconductor and are registered trademarks of Semiconductor Components Industries, LLC (SCILLC).
