NCP303151 Integrated Driver and MOSFET with Integrated Current Monitor Description The NCP303151 integrates a MOSFET driver, highside MOSFET www.onsemi.com and lowside MOSFET into a single package. The driver and MOSFETs have been optimized for highcurrent DC DC buck power conversion applications. The NCP303151 integrated solution greatly reduces package parasitics and board space compared to a discrete component solution. Features Capable of Average Currents up to 50 A 30 V / 30 V Breakdown Voltage MOSFETs for Higher Long Term PQFN39 Reliability MN SUFFIX CASE 483BF HighPerformance, Universal Footprint, CopperClip 5 mm x 6 mm PQFN Package Capable of Switching at Frequencies up to 1 MHz MARKING DIAGRAM Compatible with 3.3 V or 5 V PWM Input Responds Properly to 3level PWM Inputs Precise Current Monitoring NCP 303151 Option for Zero Cross Detection with 3level PWM AZZYYWW Internal Bootstrap Diode Catastrophic Fault Detection Thermal Flag (OTP) for OverTemperature Condition NCP303151 = Specific Device Code OverCurrent Protection FAULT (OCP) A = Assembly Location UnderVoltage Lockout (UVLO) on VCC and PVCC ZZ = Wafer Lot Supports Intel Power State 4 YY = Year WW = Work Week Applications Desktop & Notebook Microprocessors ORDERING INFORMATION Graphic Cards Routers and Switches Device Package Shipping NCP303151MNTWG 5x6 PQFN 3000 / Tape & Reel For information on tape and reel specifications, including part orientation and tape sizes, please refer to our Tape and Reel Packaging Specification Brochure, BRD8011/D.
