NCV8877 Non-Synchronous Boost Controller

onsemi NCV8877 Automotive Start-Stop Non-Synchronous Boost Controller is designed to supply a minimum output voltage during Start-Stop vehicle operation battery voltage sags. The controller drives an external N-channel MOSFET and uses peak current mode control with internal slope compensation. The IC incorporates an internal regulator that supplies a charge to the gate driver. Protection features include cycle-by-cycle current limiting and thermal shutdown. The onsemi SOIC-8 packaged NCV8877 offers low quiescent current sleep mode operation and boost operation initiates when the supply voltage drops below the regulation set point. The NCV8877 is enabled when the supply voltage drops below the wake-up threshold.
