NCV51511PDR2G ON Semiconductor

High-Frequency, High Side and Low Side Gate Driver NCV51511 The NCV51511 is high side and low side gatedrive IC designed for highvoltage, highspeed, driving MOSFETs operating up to 80 V. The NCV51511 integrates a driver IC and a bootstrap diode. The www.onsemi.com driver IC features low delay time and matched PWM input propagation delays, which further enhance the performance of the part. The high speed dual gate drivers are designed to drive both the 8 highside and lowside of NChannel MOSFETs in a half bridge or 1 synchronous buck configuration. The floating highside driver is SOIC8EP capable of operating with supply voltages of up to 80 V. In the dual CASE 751AC gate driver, the high side and low side each have independent inputs to allow maximum flexibility of input control signals in the application. MARKING DIAGRAM The PWM input signal (high level) can be 3.3 V, 5 V or up to V DD logic input to cover all possible applications. The bootstrap diode for 8 the highside driver bias supply is integrated in the chip. The V51511 highside driver is referenced to the switch node (HS) which is ALYW typically the source pin of the highside MOSFET and drain pin of the lowside MOSFET. The lowside driver is referenced to V which is SS 1 typically ground. The functions contained are the input stages, UVLO protection, level shift, bootstrap diode, and output driver stages.
