资 源 简 介
The NCV8877 is a Non-Synchronous Boost controller designed to supply a minimum output voltage during Start-Stop vehicle operaTIon battery voltage sags. The controller drives an external N-channel MOSFET. The device uses peak current mode control with internal slope compensaTIon. The IC incorporates an internal regulator that supplies charge to the gate driver. ProtecTIon features include， cycle-by-cycle current limiTIng and thermal shutdown. Additional features include low quiescent current sleep mode operation. The NCV8877 is enabled when the supply voltage drops below the wake up threshold. Boost Operation is initiated when the supply voltage drops below the regulation set point.
